The CliQ M series is designed with the latest feature in the CliQ family of products: the Advanced Power Boost (aka APB). The APB feature is useful when multiple loads are connected in a system and a large outrush current could be drawn due to one fault load. This will be detected by APB. The APB feature will trip the circuit breaker on the current path of the fault load due to high current. This prevents the system from shutting down while the other connected current paths continue to operate without interruption.
