Disconnects
Power Module™ — all-in-one elevator disconnect
The Power Module™ is the best choice for design
engineers or electrical contractors that need to meet these
requirements, Codes and standards:
• Elevator Shutdown – ANSI/ASME A17.1 Rule 102.2(c)(3)
• Shunt Trip Voltage Monitoring – NFPA 72-1999 3-9.4.4
• Integrity Monitoring – NFPA 72-1999 3-9.2.1
• Allows Elevator Shutdown – NEC^® 620.51
• Selective Coordination – NEC^® 620.62
• Auxiliary Contact (Hydraulic Elevator) – NEC^® 620.91(C)
• Orderly Shutdown – NEC^® 240.12
With the Power Module You Get:
• Shunt trip capability
• Selective coordination
• Fire safety signal interface
• Shunt trip voltage monitoring
• Component protection via Low-Peak^® Class J fuses
• UL 98 Listed for 200kA short-circuit current rating
• Lockable in the open position with three lock capability
• Optional key-test switch and optional pilot light for easy
inspection
• No annual calibration or testing of overcurrent protection
required
• Padlockable for service work safety and open door
“override” for troubleshooting
Notes: A lways follow established safety practices when wo rking
on a electrically live equipment.

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 main-
tenance of the elevator and hoistway.
