The Eaton Industries MCCB motor protection circuit breaker measures 95x90x201mm and features a setting range of 32-40A for overload protection, with a nominal continuous current Iu of 40A. The device is built as an insertable in-built device, with a unique connection method for the main circuit. The circuit breaker uses a thermomagnetic cutoff technique and has an IP protection grade of IP20. It belongs to the NZM series and covers all applications with just four compact sizes, tailored for the IEC market. With flexible mounting due to modular function groups, the circuit breaker also comes with phase-failure sensitivity, a tripping class of 10A, and meets the requirements of IEC/EN 60947-4-1 and IEC/EN 60947-2 for AC-3 switching category.
