IKI-35_24V

The IKI-35 is a compact overcurrent protection relay and is suitable as overload, short-circuit and earth short-circuit protection in combination with circuit breakers or power isolators, as well as overload protection in combination with load disconnectors and HRC fuses. The IKI-35 can be parameterized via menu or software.Current transformer supplied protection relay
