Eaton 3P 50A Circuit Breaker Motor Protection – 115451

The Eaton Industries MCCB motor protection switch measures 90x88x145mm and features a setting range for overload protection of 40 – 50A, along with a nominal continuous current Iu of 50A. The device comes in a fixed built-in design, with a unique connection method for the main circuit. It utilizes a thermo-magnetic cut-off technique, offering a protection degree of IP20. As part of the NZM series, this compact circuit-breaker is suitable for the IEC market, offering flexible mounting options thanks to its modular function groups. It includes thermomagnetic releases for motor protection, phase-failure sensitivity, and a tripping class 10A. This circuit-breaker meets all requirements of the switching category AC-3 as per IEC/EN 60947-4-1, IEC/EN 60947-2 standards.
