ACS Contactors CA 7

Compact without compromise Compact without compromise is the best way to describe the CA 7 range of contactors and motor protection relays from Sprecher + Schuh. Despite of the compact dimensions, the CA 7 range features high breaking capacity and extraordinary flexibility. Up to 18.5 kW the contactors are only 45 mm wide and even the largest 45 kW frame is only 72 mm wide. CA 7 contactors are the main component in the Advanced Control System (ACS). Top With CA 7 you have flexibility with auxiliary contacts Common auxiliaries in the CA 7 range 9 to 85 amp Three fitting positions Front mounting. Side mounting left. Side mounting right. Alternatively you can choose to combine left, right and front mounting auxiliary contacts to achieve your requirements. Instead of the top mounted auxiliary contacts, on or off delay timing modules or mechanical latches can be fitted. With CA 7 you have more clip-on accessories CA 7 common accessories, from 9 to 85 amp On and off delay pneumatic timers. Coil mounted electronic timers, on delay, off delay, star-delta. Coil mounted 24/48 V DC interface. Coil mounted RC and varistor suppressor modules. Mechanical latch. Mechanical interlock. Mechanical interlock with integrated N/C interlock contacts. Moulded wire link sets for DOL, reversing and star-delta starters. Choice of front and side mounting auxiliary contacts. Top Coil terminals always in the correct position The coil terminations on CA 7 contactors can be supplied optionally at the top or bottom of the contactor. It is also a simple task to change this arrangement on-site should the requirements change. When CA 7 contactors are used in combination with KTA 7 motor circuit breakers the bottom coil terminations are used. When used with standard CT 7 thermal or CEP 7 electronic overloads the top coil terminals should be selected. Top Space saving mechanical interlocks Only 9 mm wide, the CM 7 mechanical interlock snaps into place between any of the CA 7 contactors. You can also interlock different sizes of the CA 7 range with the same interlock. The basic mechanical interlock is supplemented by a variation with built-in N/C auxiliary contacts for electrical interlocking. This version is also only 9 mm wide and further minimises space requirements. Top CA 7 contactors provide improved wiring terminals The main terminals of all CA 7 contactors are designed to accept at least two cables. At the same time they comply with safety standards regarding touch protection. The larger contactors CA 7-30 and upwards employ a special cage terminal which allows the connection of two cables in separate chambers. The ease of wiring with CA 7 contactors saves both time and money. Top CA 6 1000 volt contactor system CA 6 contactors offer the latest in switching technology up to 1000 volts, from Sprecher + Schuh. The development of the CA 6 range now covers the CA 6-95 to the CA 6-420, the complete range covering 1000 volt, AC 3 ratings up to 225 kW, with 400/415 volt ratings up to 500 kW. Special design features of these contactors include a unique electronically controlled mechanism (ECM) which is standard on all sizes. The thermal overload relays CEF 1 and CET 5 electronic motor protection relays are also rated at 1000 volt. They are ideally suited for combining with the CA 6 and CA 5 contactors providing a choice of quality motor protection solutions. For contactors CA 6-210 and above the standard protection can be CEF or CET 5 electronic motor protection. Top High current contactors CA 5 The CA 5-370 to CA 5-860 high current contactors, combine high switching currents up to 1000 volts together with low coil power consumption, due to a specially designed coil and magnet system. These rugged and reliable contactors extend the 1000 volt switching capabilities of Sprecher + Schuh contactors up to 550 kW, as well as being suitable for AC 3 400/415 volt applications up to 500kW.
