Eaton NZMB2-S160 3P 160A Circuit Breaker – 265737

The Eaton Industries NZMB S circuit-breaker is suitable for continuous operation with a nominal current of 160A. It boasts a nominal cut-off power of Icu at 400 53kA and overload protection settings ranging from 1210 to 2000A. Similarly, the short-circuit setting range is between 1210 to 2000A. This circuit-breaker features a screw connection for the main circuit and has three poles. Moreover, it comes equipped with magnetic short-circuit release paired with an overload relay and allows short-circuit release without overload tripping. It is worth noting that this circuit-breaker meets all requirements of the AC-3 switching category. Only four compact sizes are available, but modular function groups permit flexible mounting.
