MasterPact MTZ Active MTZ2 fixed for MicroLogic X,
3P 1250A 42kA/415VAC
This is a basic frame for 3 poles MasterPact MTZ2 12N1 fixed 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 1250A. The maximum operational voltage is 690VAC 50/60Hz. The breaking capacity (Icu) is 42kA rms at 415VAC 50/60Hz. This basic frame is compatible with MicroLogic X control unit which has 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 422mm (W) x 352mm (H) x 300mm (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.
