Allen-Bradley - IntelliVAC Latched Contactor 7 - 1502-VC8DXDB-5

The mechanical latch contactor operates in much the same manner as the electrically held version with a few exceptions, once the contactor is closed, a spring-loaded mechanism moves a roller against the armature plate to hold it against the electromagnetic core. The contactor can be opened electrically by energizing a trip coil (via IntelliVAC and IntelliVAC Plus open output) which pulls the latch away from the armature or by a push button mounted on the power cell door that mechanically releases the contactor.
