Better Performances in Demanding Duties

The circuit breaker plays a vital role in distributing power and protecting the circuit and power equipment from overloading, short circuits, and undervoltage failure damage. They can also be used in electric motors for infrequent starting and overload protection as well as protection against short circuiting and undervoltage conditions.

Small volume, high breaking capacity, short arcing and anti-vibration.
