CNKA  mechanical interlock circuit breaker Introduction


CNKA's advanced mechanical interlock circuit breaker is a compact, manually operated dual power transfer switch. It ensures switching protection between the main power supply and backup power supply lines by allowing only one side to be closed at a time while keeping the other disconnected.

This mechanical interlock circuit breaker finds extensive application in specialized environments such as industries, shopping malls, shops, hospitals, mines, schools, and government agencies where dual main lines are essential. It is typically used alongside voltage regulators and other electrical equipment to ensure uninterrupted power supply and operational reliability.
