The Eaton Industries MCCB motor protection switch, measuring 90×84.5x145mm, is a built-in device suitable for continuous currents of 63A. Its shutdown technology is magnetic with a protection degree of IP20. The operative voltage is 690V. The NZM series circuit-breakers offer application coverage with just four compact sizes, suitable for the IEC market. Modularity ensures flexible mounting with the magnetic short-circuit release linked to an overload relay and a short-circuit release without overload trip. These circuit-breakers comply with all requirements of the switching category AC-3.
