Note:
Main circuit breakers in 240/277 V Sensor IQ panels do not add to the series SCCR
of the panel but serve as convenience disconnects. A 200 A Main Fuse Kit that raises
the series rating of the panel to 65 kA is available (240/277 V panels only). See

Note:
Main circuit breaker kits for 240/277 V Sensor IQ panels are custom items. If you
want to use a main circuit breaker as a convenience disconnect, please contact the
