Eaton Moeller series NZM - Molded Case Circuit Breaker

Circuit-breaker, Motor protection, IEC, Fixed, Electronic release, IEC/EN 60947-4-1, IEC/EN 60947-2, The circuit-breaker fulfills all requirements for AC-3 switching category., R.m.s. value measurement and “thermal memory”, adjustable time delay setting to overcome current peaks tr: 2 – 20 s at 6 x Ir also infinity (without overload releases), All AC-3 rating data applies to direct switching by the circuit-breaker under normal operating conditions. If, for example, a contactor takes over AC-3 switching under normal operating conditions, the full rated uninterrupted current applies to the circuit-breaker, In = Iu., 3 pole, Screw terminal, Rated current = rated uninterrupted current: In = Iu 550 A, Ii = In x … 2 - 14
