Eaton Circuit Breaker 3 Pole 50A Model NZMN1-A50 – 259082

The Eaton Industries NZMN A is a circuit-breaker featuring three poles. The device comes with a switching capacity of 400/415 V 50 Hz (Icu) equating to 50 kA and is rated for a continuous current (In= Iu) of 50 A. The breaker’s overload protection setting range is 40 – 50A and its non-delayed short circuit setting range is 300 – 500A. The device is designed to be fixed and comes with a box terminal. The circuit-breaker, which is set up to conform with IEC standards, serves a dual purpose as it provides both system and cable protection.
