It is a 3 poles switch disconnector MasterPact MTZ2 20HA in drawout version. MasterPact MTZ is the last generation of high current air circuit breakers and switch disconnectors 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 2000A. The maximum operational voltage is 690VAC 50/60Hz. The rated making capacity (Icm) is 145kA peak at 690VAc within AC-23A category. The rated short-time withstand current (Icw) is 66kA rms/1s within AC-23A category. The basic frame must be associated with the corresponding chassis which has also to be ordered separately. It can be equipped with a variety of optional functions and accessories. The dimensions are 441mm (W) x 439mm (H) x 403mm (D). MasterPact MTZ switch disconnector is compliant with international standards IEC/EN 60947-1 and IEC/EN 60947-3. MasterPact MTZ can be used in EcoStruxure architecture system. MasterPact MTZ is part of the global Schneider environmental data program.
