The Eaton Industries MCCB power circuit breaker is rated for a nominal continuous current (In = Iu) of 125A and a nominal voltage of 690V. Its nominal shutdown capacity (Icu) at 400V is 150kA. It has an overload protection setting range of 125A, a temporarily delayed short circuit setting range of 750 – 1250A, and an undelayed short circuit setting range of 6 – 10A. For the NZM2 model, the switching capacity is rated at SCCR 480Y/277V 60Hz (Icu) of 150kA, SCCR 600Y/347V 60Hz (Icu) of 50kA, and SCCR 480V 60Hz (Icu) of 100kA. The unit incorporates a box terminal and is designed for fixed installation. It complies with UL/CSA and IEC standards and its primary protective function is system and cable protection.
