EATON - MOELLER

Circuit-breaker, 3p, 90A

Delivery programme Product range Circuit-breaker Protective function Motor protection Standard/Approval IEC Installation type Fixed Release system Electronic release Construction size NZM2 Description 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.
