QBMIK for PowerPact Q-frame For use with two PowerPact Q-frame circuit breakers. The QBMIK
interlocking system allows only one circuit breaker to be On at any given
time.
Use the QBPAL or QBPALF handle padlock kits with this device to be able
to padlock one of the circuit breakers in the On or Off position.
Interlocking with Rotary Handles
S29369 for PowerPact H- and J-frame
and S32621 for PowerPact L-frame
Schneider Electric also offers an interlocking kit for applications where
rotary handles are installed. The interlock mechanism inhibits the two
devices from being On at the same time, but allows for both devices to be
Off simultaneously. The padlock provision on the rotary handles allows each
circuit breaker to be padlocked in the Off position.
