Eaton Circuit Breaker 4P 200A 125A NZMB2-4-A200/125 25KA IEC – 265853

The Eaton Industries NZMB A is a 4-pole circuit breaker with a rated uninterrupted current (In = Iu) of 200A and a nominal voltage of 440V. Its nominal interrupting capacity (Icu) at 400/415V, 50Hz is 25 kA. The NZMB A provides a setting range for overload protection between 160 – 200A and an immediate short circuit setting range of 1200 – 12000A. Designed to be a built-in fixed device, it features a screw connection. This unit is IEC standardized and serves a fundamental role in system and cable protection.
