Eaton NZM2 Circuit Breaker 4P 250A 160A 50KA IEC – 265867

The Eaton Industries NZM2 is a 4-pole circuit-breaker, featuring a rated uninterrupted current (In = Iu) of 250A, with a voltage rating of 690V. It has a considerable switching capacity of 400/415 V 50 Hz (Icu): 50 kA, thereby offering a high level of protection. It offers an adjustable range for overload protection from 200 – 250A and an immediate short circuit setting range of 6 – 10A. Designed for fixed installation, it employs a screw connection and aligns with IEC standards. Its primary function is to provide robust system and cable protection.
