THE Sprecher + Schuh CA 7 contactor range, available from NHP Electrical Engineering Products , covers up to 85 amps in four frame sizes whilst maintaining an overall width of just 45mm up to 37 amps.
CA 7 meets the IEC criteria for positively guided (mirror) and mechanically linked contacts with both front-mounted or side-mounted auxiliary blocks.
This makes them suited for use in safety control circuits.
An extensive range of common accessories reduce inventory whilst providing complete flexibility in meeting the demands of most control philosophies.
A mechanical interlock is included which can be used between two contactors of differing frame sizes to accommodate the requirements of multi-speed starters.
Other accessories include auxiliary contacts, interface and suppression modules, mechanical latch, timing modules and a mechanical interlock incorporating auxiliary contacts for electrical interlocking.
CA 7 is an integral part of Sprecher + Schuh's ACS system of components which is a specially coordinated system encompassing motor circuit breakers, overload relays, motor protection relays, control relays and a busbar connection and mounting system.
NHP also supplies CA 6 and CA 5 Sprecher + Schuh contactors to extend the range to 1200 amps and offer total solutions for motor control and protection applications. NHP 03 9429 2999.
