This is a basic frame for 4 poles MasterPact MTZ1 10H3 drawout circuit breaker. MasterPact MTZ is the last generation of high current air circuit breakers up to 6300A embedding advanced digital technologies. MasterPact MTZ is designed to protect electrical systems from damage caused by overloads, short circuits and equipment ground faults. The rated current is 1000A. The maximum operational voltage is 690VAC 50/60Hz. The breaking capacity (Icu) is 66kA rms at 415VAC 50/60Hz. This basic frame is compatible with MicroLogic X control unit which has to be ordered separately. The basic frame must be associated with the corresponding chassis which has also to be ordered separately. With MicroLogic X control unit, MasterPact MTZ contributes to safety and energy efficiency. It can be equipped with a variety of optional functions and accessories. The dimensions are 358mm (W) x 322mm (H) x 291mm (D). MasterPact MTZ circuit breaker is compliant with international standards IEC/EN 60947-1 and IEC/EN 60947-2. MasterPact MTZ and MicroLogic X can be used in EcoStruxure architecture system. MasterPact MTZ is part of the global Schneider environmental data program.
