3 and its commitment to protecting the environment is one of the forerunners among the companies in the Group in dedicating considerable resources towards reaching its objectives of sustainable development and environmental protection. This is confirmed by the fact that all the company manufacturing sites have been awarded ISO 900 quality certification and most of them have also been awarded ISO 00 environmental management system certification. The plants in Frosinone and Patrica have also been awarded the Quality, Environment and Safety Integrated System certification and are certified in compliance with the BS 8800 Standards for health and safety in the workplace. is actively involved in continuing the policy of improving environmental management by rationalizing the consumption of raw materials and energy, preventing pollution, respecting water and air, reducing noise levels to a minimum, reducing waste from production processes and carrying out periodic environmental checks at the main suppliers premises. By using analysis tools such as LCA (Life Cycle Assessment), from the initial design stages assesses and improves the environmental performance of its products throughout their entire life cycle in order to guarantee maximum efficiency in technical and energy performance during operation, control and reduce environmental impact in the manufacturing stage and define end-of-life procedures. All these goals and activities are the result of a far-sightedness in adopting ecological policies and methods of reducing environmental impact and, here too, is, as already seen in the quality of its products, a leader on the Italian company scene. 0/

5 System pro M modular devices for low voltage installations System pro M is a modular system developed by ABB which is capable of meeting the requirements of the most modern and up-to-date installations for low voltage applications. Project criteria The system is based on two main criteria: complete functionality and optimum sizing of the devices. The first means there is a wide range of devices which leads to increased safety for the user and greater diversification in command and load management; the second, based on the modular structure, allows the internal space of the switchboard to be used in the best possible way, reduces wiring operations and improves functionality and also the aesthetics of the switchboards. Functions Protection, command, measure and load management: for each of these four basic functions which characterize the low voltage electrical applications, the System pro M series proposes the right device. The protection sector which is the basis of the system consists of MCBs, RCBOs, RCCBs and RCD blocks. These miniature modular devices are technologically advanced, which speeds up installation and simplifies maintenance. 0/

6 System pro M modular devices for low voltage installations Standards and certification Each device in the System pro M series has been designed in accordance with strict criteria for safety and functionality in compliance with the dictates imposed by international, European and Italian Standards. For this reason, the devices in the System pro M series have obtained standardization issued by the certifying bodies both in Italy and overseas. Tropicalization All the devices in the System pro M series, and especially those used for protection, have been carefully designed and constructed to guarantee the maximum operating safety even in difficult environmental conditions. According to the type of device, the metal parts of the switching mechanisms are protected with a suitable galvanic coating or are made of stainless steel to avoid oxidation which may impair operating; even the conductive parts are protected by galvanic coating. The tropicalized devices can withstand the test conditions established in the relevant current Standards (VDE DIN 006, IEC 68., DIN 5006). 0/5

7 Unifix cabling system Unifix cabling system: the ideal complement for the System pro M range Unifix is the ABB cabling system which makes the work of installers and switchboard builders easier: with its standard connectors, Unifix effects simple, quick and safe wiring of System pro M modular devices and SACE Isomax S and S and Tmax T T moulded-case circuit-breakers in ArTu switchboards and ABB consumer units. For this reason, it is the ideal solution for using pro M modular products to best advantage and exploiting the fact that ABB products for low voltage applications can be perfectly integrated whilst at the same time guaranteeing safety and full compliance with Standards. Special features The main feature of Unifix lies with the possibility of combining different types of circuits (one-phase/three-phase/auxiliary) in a single module. Pre-wiring can be effected at the workbench and installed in the switchboard subsequently, with no limits to the type or combination of devices which can be installed. Unifix has adjustable pitch which replaces traditional wiring harnesses which means that circuit-breakers with different polarities can be placed in the same row as well as auxiliary modular devices. The fact that Unifix integrates perfectly with the different ABB low voltage products, both modular and moulded-case devices, switchboards or insulating consumer units, ensures that all devices and accessories can be quickly selected and installed. The system consists of three series H, L and SL. Each one is suitable for specific applications both for the installation of devices and installation in switchboards. In detail: - the H series, intended for more demanding applications, is used for wiring SACE Isomax S and S and Tmax T T mouldedcase circuit-breakers and System pro M modular devices in ArTu switchboards (rated currents up to 00A and short-circuit currents up to 50kA); - the L series is the universal solution for wiring System pro M modular devices in ArTu switchboards and polycarbonate consumer units (rated currents up to 00A and short-circuit currents up to 5kA); - the SL series is the ideal easy and cheap solution for wiring bipolar modular devices in consumer units (rated currents up to 0A and short-circuit currents up to 0kA). N.B. The Unifix cabling system can be used with devices only. 0/6

8 Unifix cabling system ONE SYSTEM, MANY ADVANTAGES Considerable reduction in wiring times: by using rigid lock connectors which are standardized for the different types of device, each device does not have to be connected using cables Greater standardization of low voltage switchboards: the rigid connectors enable the results of the type tests (overheating and short-circuit) effected by ABB to be extended also on input wiring of devices. A more advanced and, at the same time, cheaper technical solution compared with traditional wiring. This is made possible by cutting down on materials (wires and wire terminals) and space required, thus affecting operating times Can be used on all ABB standard devices, without modifying or adding accessories and without using special equipment 5 Adjustable pitch: Unifix uses adjustable pitch unlike traditional wiring harnesses; in this way, circuit-breakers with different polarity can be placed in the same row as well as auxiliary devices 0/7

12 Protection, command, load management and measurement modular devices General s modular devices are installed on the load side of the main circuit breaker for better use of electricity in all kinds of applications. Along with MCBs and RCDs, they carry out numerous functions to suit the needs of any plant in the residential, tertiary and industrial fields. Protection In addition to MCBs and RCDs, supplies other modular devices for protection such as residual current relays and fuse holders. Command This category includes devices that are operated manually to command the electric system: contactors, latching relays, switch-isolators, switches, pushbuttons etc. Typically they are installed to control lights from several points of the same circuit or to pilot user devices with a high number of operations. Load management Overload relays, load management switches, anti black-out lamps, time switches and the other modular devices in this category react automatically to variations of parameters and other events in the system to allow for plant optimisation. Measurement The range of devices in this category is very wide, including a great number of auxiliary components and accessories that make installation in switchboards and consumer units practical and economic. Other functions The range of s MDRCs also includes bells, transformers, sockets etc. /

66 Technical details Protection devices RD RESIDUAL CURRENT MONITORS They operate combined with appropriate toroidal transformers (in 9 different diameters) which perform the sum of line currents; any current leakage in the monitored circuit causes, in the secondary of the toroidal transformer, a signal detected by the relay which intervenes. The relay can command the tripping of the protection circuit-breaker release, thus breaking the circuit. According to the IEC 008 or EN 6008 Standard, these relays are sensitive to leakage sinusoidal currents and to leakage pulsating currents with direct components. Thus they can be defined as A type. Some electric circuits allow to adjust sensitivity and time; the values can be selected through appropriate minidips.

Connections Screw terminal boards, max. section.5 mm Protection degree Any IP0 Generality They must be mounted with residual current monitors upstream the lines or loads to be protected; all active conductors (phases and neutral) of single-phase as well as of three-phases lines must pass through them. In this way these devices perform the vector sum of line currents detecting the possible homopolar differential currents that leak to earth: their core of sheet iron has high magnetic properties that allow to detect even very low leakage currents. The choice of a toroidal transformer depends on the conductor or on the bar to be used. It is suggested to use the openable versions in case of revamping or upgrading of an existing installation. Installation All active conductors can be introduced in the toroidal transformers without the need of respecting any specific sense of introduction (P-P or P-P). The output signal must be picked up from terminals (S) and (S) and connected to the residual current monitor, while terminals and must be connected to the test output of those relays of MFPP range with this function. With RD they must remain disconnected. For this connection it is better to use twisted or shielded cables, possibly far from busbars. The minimum recommended section of connection cables should have a maximum resistance of Ω; anyway consider a maximum length of connection of 0 m for 0.5 mm and of 00 m for.5 mm. For versions with openable core it is necessary to control that the contact surface of the two semicores is clean, that bolts are tight and that connection cables connections on both sides are intact. Connection cables with metallic shielding or armor must be earthed downstream the toroidal transformer; if they run within the transformer they must be earthed in the opposite direction. /
