MINIATURE CONTACTORS AND STARTERS
Series CA8 Contactors and CAT8 Starters up to 7.5 HP
An Ingenious Miniature Contactor and Starter System
The CA8 miniature contactors and starters provide an extremely compact and reliable method of controlling motors of 7.5 HP or less (@460V). The CA8 contactor is an economical choice for applications where space is limited or where a minimal enclosure is desired. Components are DIN-rail mountable for instant installation and modification. Fittings are also included on the CA8 for base mounting. All terminals are clearly marked and shipped in the open position for installation with either manual or power screwdrivers.
Small and 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 CA8 have an electrical life of 700,000 operations, while the AC magnet system has a mechanical life of 10,000,000 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.
The CL8 Ecombo Motor Controller
Sprecher + Schuh's newest miniature contactor is also available in a UL approved motor circuit control, in reversing and non-reversing models for AC and DC control power. This compact and versatile controller can reduce panel space and offers a variety of control schemes in an easy to install, state-of-the-art combination starter assembly that includes the Type F KT7 Self-Protected, Combination Motor Circuit Controller.
Accessories require no additional panel space
The entire CA8 System is logically engineered. Modular accessories like auxiliary contact blocks snap-on without increasing the CA8'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 use of enclosures with shallow mounting depths. Once the CA8 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.
