Switch suitable as manual motor controller

May 2006 Operator Interfaces, Switches & Relays

The AC versions of the AS168X (trip characteristics F, G and H) can also be used now in the current range from 0,5 to 30 A as manual motor controllers for direct control of motors connected across-the-line (direct-on-line). UL 508 and CSA 22.2 No.14 are satisfied for the application as a manual motor controller intended for use as a motor disconnect. The approvals of UL 1077, CSA 22.2 No.235 and EN 60950 remain valid. This means that the AS168X can be used as a circuit breaker of equipment (CBE) or as a manual motor controller (MMC):

* Suitable as motor overload protection (thermal and magnetic).

* Suitable as motor starting across-the-line (direct-on-line).

* Suitable as motor starting with motor disconnect (cos phi 0,4-0,5).

* Suitable as motor group installation (short circuit capacity 5 kA).

* Suitable for control circuits in order to derive the rated current of the AS168X from a motor capacity, the approval includes a HPRating (Horsepower).
