3 A Series and CAT8 Starters An ingenious miniature contactor and starter system Sprecher + Schuh s New Series of miniature contactors and starters provide an extremely compact and reliable method of controlling motors of 7.5 HP or less (@460V). The is an economical choice for applications where space is limited or where a minimal enclosure is desired. Small but rugged Even though their contacts and coils are not replaceable, Sprecher + Schuh has subjected this series of contactors to monitored endurance tests that demonstrate their ruggedness. At full load, under 3-phase power, the contacts in the have an electrical life of 700,000 operations, while the AC magnet system has a mechanical life of 15,000,000 operations. The CAT8 Starter Efficient and reliable This miniature starter features the new CT8 Thermal Overload Relay. A complex current limiting calibration procedure performed after each unit is what ensures the consistent high quality of Sprecher + Schuh s thermal overload relay. Today s, Class 10 T-frame design like the CT Series has been recognized by many motor manufacturers as the ideal type to assure optimum motor protection due to less use of copper and iron. use of enclosures with shallow mounting depths. Once the is installed, all auxiliary contact blocks can be snapped-on or removed without changing any existing power wiring. Other accessories include a snap-on RC Link (surge suppressor), mechanical interlocks and space saving adaptors for connecting auxiliary components. Effortless installation Both the Contactor and the CAT8 Starter are DIN-rail mountable for instant installation and modification. Fittings are also included on the for base mounting. All terminals are clearly marked and shipped in the open position for installation with either manual or power screwdrivers. Accessories require no additional panel space CAT8 starters feature the new CT8 thermal overload. The entire System is logically engineered. Modular accessories like auxiliary contact blocks snap-on without increasing the s original width of 45mm. Also, due to its horizontal switching movement, the basic contactor has the same low profile whether an AC or DC operating magnet is used. This permits the 45mm ( 1 7/16 ) 9A 12A A145.1

4 Series Miniature, Starters, Overloads & Industrial Relays A Rated 690V RoHs Compliant Conforming to U.S., Canadian, and IEC Standards Same Dimensions for AC and DC Pluggable Surge Suppressor Modules Suppressor modules are simply plugged on the front of the contactors, next to the auxiliary contact blocks. No wiring required. Fast and easy installation. Auxiliary Contact Reliability Bifurcated, AgNi (silver/nickel) plated contacts for high contact reliability for 15V/2 ma electronic signals. H-shaped self cleaning auxiliary contacts provide a 4-way current path ensure high contact reliability for low energy switching. A145.2

6 Catalog Number Coding Open Catalog Number Coding Sprecher+Schuh employs a catalog number coding system for contactors (and many other devices) that follows a logical pattern, where every digit signifies a specific device attribute. Where indicated, the use of dashes ( ) serves to separate device characteristics and should always be used when ordering. The following example illustrates all of the possible combinations when specifying contactors and reversing contactors (open type only).

24 Series CT8 Thermal Overload Relays Simple and effective motor protection for applications to 7 1 /2HP@ 460V (10HP@575V) Sprecher + Schuh has been a leader in providing superior motor protection. The new CT8 is an economical thermal overload relay yet includes proven features like Differential tripping, Automatic / Manual reset modes, and isolated alarm circuit contacts as standards. Consistent and reliable protection The consistent high quality of Sprecher + Schuh thermal overload relays is ensured by a complex current calibration procedure performed after each unit is at full operating temperature. Calibration is performed at the largest and smallest current the overload can handle. The accurate time/ current characteristic curve obtained in this manner guarantees reliable motor protection every time. Ambient temperature compensation All Sprecher + Schuh thermal overload relays are temperature compensated. An additional bimetallic ambient compensation strip, built into the conductor-bimetal transmission path, ensures that the tripping characteristics of the relay remain constant over an ambient temperature range of 25 C to +50 C. Single phase applications CT8 Series thermal overload relays can be applied for protection of single phase AC motors. The relays have the same characteristics as shown for three phase operation. To maintain these characteristics, each element of the overload relay must carry the motor current as shown in the schematic on page C88. B Motor Protection CT8 Superior Class 10 characteristics Today s T-Frame motors have less copper and iron that the old U-Frame motors that were popular when traditional Class 20 overload relays were designed. For this reason, faster Class 10 overloads like the CT8 Series have been recognized by many motor manufacturers as the ideal type to assure optimum protection of T frame motors. Protection from single phase conditions A unique feature not found in traditional thermal overload relays provides accelerated tripping under single phase conditions. This is accomplished with a special differential tripping mechanism built into CT8 (see illustration at right). Other standard features CT8 thermal overload relays feature a fail-safe trip-free design that prevents the device from being held closed during an overload. In addition, a selectable lever permits the user the option to choose the manual or automatic reset modes. A separate NO signal contact is also provided on CT8 overloads which is isolated from the NC trip contact. This permits the use of a trip signal voltage different than that of the control voltage. Sprecher + Schuh provides outstanding motor protection with our CT8 Thermal Overload Relay CT8 Thermal Overload Relays offer accelerated tripping under single phase conditions B32.1

30 CS8 Industrial Control Relays The miniature relay system with big advantages CS8 front mount auxiliaries are positive guidance Despite increasing complexity, control systems and installations must become increasingly compact. And the CS8 Miniature Relay System packs maximum performance into minimum space. Small but rugged Sprecher + Schuh has subjected this relay series to monitored endurance tests that demonstrate their ruggedness. Under normal duty, CS8 contacts have an electrical life of 700,000 operations, while the AC magnet system has a mechanical life of 15,000,000 operations. The coil is designed for absolute undervoltage reliability. Undervoltages that do not cause the contactor to close can be withstood indefinitely without damage. The body of the device is sturdy as well. The front housing, containing the phase partitions and screwdriver guides, is manufactured in one piece. Front and rear housing are then joint fitted together. Superior Contact Reliability The standard CS8 base relay and auxiliary contacts are bifurcated H-bridge design which divides each movable contact into two sections at the tip of the spanner which provides a higher degree of reliability for low signal applications. Perfect fit for PLC and other electronic circuits operate at signals as low as 2mA. Accessories require no additional panel space all auxiliary contact blocks can be snapped on or removed without changing any existing wiring. Auxiliary components provide flexibility CS8 auxiliary components allow you to convert the basic four pole relay up to an 8 pole relay. Effortless installation CS8 relays are DIN-rail mountable for instant installation and modification. Fittings are also included for base mounting. All terminals are clearly marked and shipped in the open position for installation with either manual or power screwdrivers. Using self-adhesive labels, or plastic clip-on tags. The entire line is culus Listed and CE Certified and offers finger and back of hand protection to the strictest international standards. G Control & Timing Relays CS8 The entire CS8 system is logically engineered. Auxiliary contact blocks are modular and snap-on without increasing the CS8 s original width of 45mm. Also, due to its sideways switching movement, the basic relay has the same low profile whether an AC or DC operating magnet is used. This permits the use of enclosures with shallow mounting depths.
