Eaton 3P 250A Circuit Breaker 36KA NZMC3-S250-AVE Withdrawable Unit – 113512

The Eaton Industries MCCB motor circuit breaker is a compact device, measuring 185x346x260mm, designed for mounting via insert form. It has a nominal continuous current rating of 250A and connects to the main circuit via a screw connection. Its magnetic interruption method ensures efficient operation, while its IP20 protection grade provides adequate resistance to everyday elements. Its operating voltage stands at 690V. The NZM..-S series circuit-breakers, which this device belongs to, comprises four compact sizes to cover all application cases for the IEC market. They are built to provide flexible mounting options due to their modular function groups. They are equipped with magnetic short-circuit release in conjunction with an overload relay, with an option for short-circuit release without overload trip. They satisfy all requirements of the switching category AC-3.
