4 Your best solution for Electrical Switching Operations Compact Contactors - CWC Developed according to international standards IEC/EN 6947 (CE) and UL 58 (USA), they meet the requirements of a wide range of applications around the world. Ideal for applications where conventional contactors are too large for the space available and where streamlined projects are necessary. Although small, they are able to switch loads up to 69 V. They present high performance in electrical switching operations, reaching over one million operations. Versions Three-pole (3NA) up to 22 AC-3 Four-pole (4NO or 2NO+2NC) up to 6 AC-3 Auxiliary (4NO, 3 NO+NC, 3NC+NO, 2NO+2NC) up to AC-5 J J Contactors with AC and DC coil with the same size up to 6 A (CWC7...6) and a wide range of coil voltages available H D W 4 Compact Contactors CWC

5 Applications The characteristics of the contactors make them suitable for applications in different segments: Wood Food Refrigeration Pumping systems Machines and processes in general Irrigation systems Buildings Illumination Vehicle barriers and automatic gates Main Certifications Compact Contactors CWC 5

6 Mechanical Interlock Mechanical interlock without addition of side space. It allows the CWC7...6 contactors to be mounted side by side, providing better use of space in panels for reversing and star-delta starters. This accessory is mounted in the front, and no tools are required for the installation. Its use does not prevent the addition of auxiliary contact blocks, surge suppressor blocks, and other accessories connected to the power terminals. Safety in Installation All the contactors have degree of protection IP2 to prevent inadvertent contacts with the live parts without requiring additional accessories. Surge Suppressor Blocks Designed to prevent current or voltage surges on the command circuit, the suppressor blocks of the CWC line were developed with the clip fastening system without using cables. The assembly and disassembly do not require any tools. Available in the versions: varistor, resistor-capacitor, diode and Zener diode. Efficiency in the Mounting The mounting on DIN rail 35 mm (EN ) provides fast and efficient installations. Its mounting base allows up to four fastening points, making the installation flexible and totally compatible with most existing contactors, simplifying its replacement by the CWC lines. 6 Compact Contactors CWC

7 Indication of Position or State Front identification of the state of the contactor by means of indicator in the place marked with I (ON) and O (OFF). Contactors, even installed with accessories, allow the view of their state. Mirror and Mechanically Linked Contacts In order to meet the requirements of the safest and most demanding machine and equipment applications, the contactors were developed according to IEC/EN Annex F, about Mirror Contacts), and IEC/EN Annex L, about Mechanically Linked Contacts". IEC/EN Symbol Mechanically Linked Contacts IEC/EN Symbol Mirror Contacts Connection Busbars Developed for customers that need to save time, avoid errors and standardize operations in the assembly of motor starters on electrical panels. Available in the reversing and star-delta versions, they also allow to add protections (MPW motor-protective circuit breakers or RW7 overload relays) together with these contactors. Built-In Auxiliary Contacts - NO or NC They meet the needs of most applications without requiring any additional contacts, reducing items in the inventory. They have self-cleaning characteristics by means of sliding contacts, providing high reliability in low voltage and current (7 V / 5 ma) switching operations. Compact Contactors CWC 7

8 Additional Contact Blocks Available in the frontal version, they allow the expansion of 4 or 2 auxiliary contacts per contactor. Assembly and disassembly without tools. They have self-cleaning characteristics by means of sliding contacts, providing high reliability in low voltage and current (7 V / 5 ma) switching operations. Numbering according to EN 55 and EN 52. Drive Control Low-consumption, direct current coils (5.8 W) enable the direct drive of the contactors via PLCs, inverter outputs or soft-starter, without using relay interfaces. Low and extremely low-consumption coils allow to reduce power supplies and command transformers, ensuring better use of the energy resources and lower costs on your electrical panel. Faster and Securer Connections The cage clamp connections of the CWC7...6 contactors provide faster installation of power cables and accessories. Using a screwdriver, it is possible to make the connections in a shorter time in comparison to screw terminals. Due to special springs on the connection terminals, retightening is not necessary, because the connection system ensures constant pressure on the cables. Wide Range of Accessories All the accessories are interchangeable between the CWC7...6 and CWCA models, enabling the optimization of items and greater flexibility of their applications. Example: the same front contact block, suppressor blocks, interlock and mechanical retention may be installed in different models of contactors. 8 Compact Contactors CWC

9 Compact Starters The most compact starters on the market up to 25 A. Contactors fully compatible with the RW7 overload relays and MPW8 e MPW4 motor-protective circuit breakers, enabling the installation of direct on-line starters up to 9.2 kw / V and star-delta starters up to 22 kw / 3 38 V. RMC Mechanical Retention Block It allows to keep the electrical contacts of the contactors operated without continuous supply of its coil. Ideal for circuits with a low number of switching operations, such as: ventilation systems, illumination, etc. The front mounting of this accessory on two contactors mounted side by side allows the mechanical retention of one contactor (K). After a command pulse on the coil of contactor K (minimum duration of ms), this accessory will keep its contacts retained. For contactor K to return to its initial state, it is necessary a command pulse on the coil of contactor K2 (RESET), releasing the mechanical retention of contactor K. If the coil of contactor K2 keeps energized, the RMC accessory will not actuate on contactor K. Accessory compatible with CWC7...6 and CWCA contactors, front contact blocks, suppressor blocks and timers. K K2 Timer Blocks Extremely compact electronic timers only 9 mm wide. They are installed on the side of the CWC contactors without tools, allowing timing between.3s and,8s (3min) at voltages of V AC/V DC. Models with Power up Delay (TEC), Power down Delay (TDC) and for star-delta starters (TETC). Compact Contactors CWC 9

10 Environmentally Friendly Manufactured with materials of low impact on the environment and according to the RoHS international requirements. Connectors for CIC Printed Circuit Boards The accessory allows mounting the CWC7...6 and CWCA contactors with screw terminal on printed circuit boards. Ideal for OEMs (automatization of vehicle barriers, automatic gates, fans, etc.) that require operations with robust components developed for specific applications, such as the switching of electric motors. Connectors manufactured with metallic terminals with special coating for better adherence of the weld and support in plastic flame resistant material. Issued by the Parliament and by the European Council, the RoHS restricts the use of hazardous substances on electronic products traded in the countries members of the EU, prohibiting the ingress of new products on the market in case they contain lead, cadmium, hexavalent chromium, mercury, polybrominated biphenyl (PBB) and polybrominated diphenyl ethers (PBDE). The CWC line complies with the RoHS requirements. Compact Contactors CWC

The compact contactors K will only return to rest position after compact contactors coil (K2) be energized by a releasing pulse. The mechanical latch will always and only happen on compact contactors (K). Note: if RESET compact contactors coil (K2) remains energized, the latching of compact contactors (K) is not enabled. 3 Compact Contactors CWC
