DESCRIPTION
The CA7 contactor series represents the most modern and flexible IEC power contactor available today. A wide selection of contactors covers the entire CA7 horsepower range (up to 75HP @ 460/575V). Six of the contactors are only 45mm wide, an extremely small footprint for such rugged performance.
A wide selection of contactors in four frame sizes covers the entire CA7 horse-power range (up to 75HP @ 460/575V). Six of the contactors are only 45mm wide, an extremely small footprint for such rugged performance. A number of design features account for this efficiency, including high contact pressure and “bounce-free” contacts, allowing the devices to handle the high starting cur- rents typical of modern motors.
The entire CA7 line features mechanically linked contacts, sometimes referred to as “positively guided contacts” or “force guided contacts”. If a main power pole welds, adequate clearances exist (≥0.3mm) to ensure that the auxiliary contacts do not change state when coil power is removed and the device tries to open. This is a requirement in safety circuits per IEC 60947-5-1. Reliability is further assured by “cross- stamped” auxiliary contacts, which provide multi-point reliability in low current, low voltage applications.
