Automatic transfer switch (АВР) 160A NXZM 160S/3B CHINT

Automatic transfer switch (АВР) CHINT NXZM-160S/3B 160A The one-piece CHINT automatic transfer switch of the NXZM series is an intelligent solution for ensuring uninterrupted power supply. The device combines two moulded-case power circuit breakers, a motor operator and a microprocessor control unit in a single compact module. The NXZM-160S/3B is designed to transfer the load automatically between the main and standby supply lines when emergency conditions occur (phase loss, overvoltage or undervoltage), ensuring continuity of operation of critical consumers. Technical parameters Manufacturer: CHINT Electric Series: NXZM Rated current (In): 160 A Number of poles: 3P (three phases) Release type: Electromagnetic and thermal Breaking capacity (Icu): 25 kA Rated operational voltage (Ue): 400/415 V AC Transfer time: less than 3.0 s Operating modes: Automatic, Manual, Remote Mechanical interlock: Built-in (prevents simultaneous connection of two incomers) Functional capabilities The built-in transfer controller continuously monitors the input voltage parameters on both incomers. The user can set the voltage operating thresholds and the transfer time delays. The device supports the self-return function (automatic transfer back to the main incomer after the supply parameters are restored) or operation without self-return (mutual standby). The front panel carries an LCD display showing the current supply parameters and a handle for manual operation in emergencies. Advantages One-piece design: The integrated construction substantially reduces installation time and the number of connecting wires in the board. Safety: Reliable mechanical and electrical interlocking positively excludes the possibility of the power sources being connected against each other. Intelligent control: The controller provides high measurement accuracy and flexible setting to suit the specific requirements of the site. Compactness: Takes up considerably less space in the switchgear than solutions based on two separate contactors or circuit breakers with an external transfer control unit. High reliability: The use of NXM series power circuit breakers as the switching elements guarantees excellent protection against short circuits. Scope of application The NXZM 160A is an ideal choice for supplying power to infrastructure facilities, small production workshops, business centres, medical institutions and large country houses. It effectively controls transfer between the municipal mains and a diesel generator set (ДГУ) or two independent feeders from transformer substations.
