The Eaton Industries MCCB motor protection circuit breaker has dimensions of 95x90x201mm and is a plug-in device with a nominal continuous current Iu of 63A. The main circuit connection method is unique and the cut-off method is magnetic, rendering a protection degree of IP20. It employs an operating voltage of 690V. The Series NZM..-S circuit breakers, in four compact sizes, are designed for the IEC market and offer flexible mounting due to their modular function groups. The device incorporates a magnetic short-circuit release conjoined with an overload relay and also features a short-circuit release without overload trip. These circuit-breakers comply with all requirements of the switching category AC-3.
