See CA7 Accessories section for applicable information. DC and AC coils are not interchangeable. are only available in 24 VDC. See pages A52-53 for limitations on adding auxiliaries to Electronic DC Coil Consumption Electronic DC coils have extremely low inrush which allows the use of smaller power supplies.

This new design results in: Lighter, lower depth More energy efficient Contactors Easier wiring Uniform panel control from PLC:The low power Consumption contactor designed to control motors and other loads is especially aligned to the specific requirement of Electronic control circuits. The low power Consumption of W/60 mA allows direct control through PLC s without the need for interposing relays.

3 This is the typical configuration when using the contactor with an overload relay. When the contactor is used with the KT7 Motor Circuit Controller, the coil must be reversed, so that the coil terminals are located at the load side (bottom) of the contactor. CA7 coils can easily be reversed in the field, however, they are also available for order with the coils reversed from the factory.

A36 SSNA9000 ContactorsACA7 Discount Schedule A-1 Contactors - Two Winding DC CoilThree Pole - Series CA7 Non-Reversing, Three Pole Contactors With Two Winding DC Coil, Series CA7 (Open type only) (D20) Contactors are supplied with one NO auxiliary in the base. Contactors are supplied with one NC auxiliary in the base. All Contactors are supplied with an extra right side mounted block, that in-cludes one auxiliary available for customer use, in addition to a 50ms late opening auxiliary contact for transition from pick-up winding to hold-in winding.

7 Have an internal auxiliary contact to transition from the start winding to the run winding. Coils include an integrated diode surge suppressor. Other coil voltages are available, see page A62. Contact your Sprecher + Schuh Sales Rep-resentative to determine which coil voltages may be stocked. Non-standard coil voltages (non-stock) must be ordered and installed separately as renewal parts. The coil codes shown are the most commonly stocked items. Contact your Sprecher + Schuh representative to determine if other voltages, , 12DD, 48DD, 220DD are on-hand or can be specially ordered in contactor (typical)Description: Contactors with two winding DC coils have very low hold-in values and share the same dimensions with AC Contactors .
