The Cooper Bussmann Quik-Spec™ Power Module Switch and Panel are factory configured to the specific application.

The Quik-Spec™ Power Module Switch (PS) for single elevator applications.

Power Module™ Panel (PMP) for multiple elevator applications.

*Fused main disconnect requires Class J fuses, not supplied with switch.

Hydraulic Elevators
Hydraulic elevators need battery backup to help prevent stranding passengers. To keep the elevator from moving when it’s been manually shut down for maintenance, the NEC® requires battery backup be connected to the elevator disconnecting means through an auxillary contact.

However, an unintended consequence can be passengers getting stranded because of devices that open automatically (circuit breakers and disconnects utilizing a molded case switch with a trailing fuse block) will operate with a fault on their loadside. That operation also disables the battery backup and strands passengers. That’s why the Power Module has a non-automatic fusible shunt trip switch. If the Power Module has a fault on its loadside, the fuses open and the battery stays enabled. Thus the Power Module ensures that battery power is enabled when the passengers need it to exit - and disabled to allow safe maintenance of the elevator and hoistway.
