ELECTRICAL MOTOR CONTACTORS
Series CA7 Contactors up to 75 HP
General Purpose And Special Purpose Starting At Just 45mm Wide
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.
Same small size for most DC applicationsThe CA7-9 to 55A contactor sizes include an Electronic DC Coil option. The Electronic DC contactor design is the same size as the AC contactors, providing a compact unit for DC applications. Very low inrush and low power consumption result in a smaller power supply and smaller panel size. Learn more from the CA7 Electronic DC literature. |
Type 1 and Type 2 Coordination
Whether you are designing motor circuits for use in North America, Europe or any other part of the world, all CA7 contactors have been designed and tested with respect to Type 1 and Type 2 short circuit coordination.
Advanced safety and reliability features
The entire CA7 contactor line features mechanically linked contacts, such that if a main power pole welds, adequate clearances exist (greater than or equal to 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.
Modular accessories are common to all devices
All accessories are interchangeable among all CA7 contactors and CS7 control relays. This minimizes inventory requirements and maximizes flexibility.
Reversible coil provides total flexibility
When shipped, both coil connections are normally located at the top of the contactor in preparation for mounting an overload relay at the bottom. For multi-starter panels, however, the coil can be reversed. CA7 contactors can either be ordered with the coil reversed or may be easily reversed in the field.
Dual power terminals speed wiring
CA7-30 through 85 contactors are designed with two power terminals for all three poles. This simplifies power wiring of interconnected contactors in reversing, reduced voltage and two-speed applications. Simplified wiring means less labor and less cost.
