Automatic transfer switch (АВР) 200A NXZM 250S/3B CHINT

Automatic transfer switch (АВР) CHINT NXZM-250S/3B 200A The monobloc automatic transfer switching device of the NXZM series is an intelligent solution that combines in one housing two moulded-case power circuit breakers, a motor operator and a microprocessor control unit. The device is designed to transfer the load automatically to the standby power source when faults occur in the main supply. The 200A model provides high reliability of power supply for category one facilities, while offering compact dimensions and simple set-up without the need to assemble complex circuits from separate contactors. Technical parameters Manufacturer: CHINT Electric Series: NXZM (monobloc АВР) Rated current (In): 200 A Number of poles: 3P (three-pole) Frame size: 250 Ultimate breaking capacity (Icu): 35 kA (S - standard) Controller type: B (basic intelligent with LCD display) Rated operational voltage (Ue): 400 V AC Transfer time: less than 3 seconds Mechanical interlock: Built-in (prevents both incomers from being closed simultaneously) Design features The device is fitted with a built-in controller with a display showing the current network parameters (phase voltages). The construction includes a single motor operator that mechanically switches the levers of the two circuit breakers. Rigid mechanical and electrical interlocks completely rule out the risk of a phase-to-phase short circuit between the two independent incomers. Three operating modes are provided: Automatic, Manual (using a removable handle) and Remote. The control terminals allow external signals for generator start-up or from the fire alarm system to be connected. Advantages Ready-made solution: No need to design complex logic and wiring — all components are already integra
