Circuit Breakers have become the go-to device for protecting circuits nationwide and have an impeccable track record of performance. The CELHK11-71165-9-V is an ideal circuit breaker for any commercial application. This device plays a critical role in any electrical system by providing protection from over-currents or short-circuits that may damage it.

The CELHK11-71165-9-V is a type C miniature circuit breaker and features an insensitive trip characteristic which means that the circuit can handle large inrush currents associated with motors or transformers. The device also allows for remote control wiring to provide external tripping or resetting of the circuit breaker. It features a control voltage of 24V rated DC current and a rated short-circuit capacity of 10kA.

In addition to its overload and short-circuit protection, the CELHK11-71165-9-V also provides a thermal-magnetic overcurrent protection. The thermal element is designed to operate automatically after a predetermined amount of energy is failure. On the other hand, the magnetic element operates when a fault current exceeds a predetermined setting. These features make the CELHK11-71165-9-V ideal for applications such as power distribution, transformer protection, and branch circuit protection.

The CELHK11-71165-9-V operates using a differential principle. This is a two-phase, three-wire system which measures current flow in each phase by connecting both phases to a current transformer. When the current in one of the phases exceeds the pre-set amperage, the differential relay is activated and the corresponding contactor opens. This causes the output contact of the differential relay to trip the circuit breaker, removing power from the circuit.

The CELHK11-71165-9-V is a great choice for any commercial application that requires a reliable circuit breaker for overcurrent and short circuit protection. This device offers a sensitive thermal-magnetic protection and its differential principle operation ensures quick tripping and resetting of the circuit breaker. Furthermore, its rugged design and construction makes it suitable for withstanding even the harshest environmental conditions.
