Schneider Electric LV848340

The MasterPact MTZ3 40H2 circuit breaker frame is engineered for 4-pole applications, accommodating a rated current of 4000A. With a maximum operational voltage of 690VAC at 50/60Hz, it features a breaking capacity of 150kA rms at 415VAC 50/60Hz. This frame is compatible with the MicroLogic X control unit, which must be ordered separately, as well as the corresponding chassis.

Designed to safeguard electrical systems from overloads, short circuits, and ground faults, this circuit breaker frame is compliant with international standards such as IEC/EN 60947-1 and IEC/EN 60947-2. The dimensions of the frame are 1016mm in width, 479mm in height, and 403mm in depth when combined with the chassis. Its operational features include a maximum breaking time of 25 ms and a mechanical durability rated for 10,000 cycles with periodic maintenance.

The frame is suited for mounting on either base plates or rails and offers a pollution degree of 3, ensuring reliable performance in various environments. The MasterPact MTZ3 circuit breaker can operate efficiently in ambient temperatures ranging from -25°C to 70°C, with storage capabilities extending from -40°C to 85°C. It is recognized as part of the Schneider environmental data program, contributing towards energy efficiency and safety in electrical installations.
