In terms of performance characteristics, Schneider NW40HA-4000A-690V-3poles has a rated current of up to 4000A and a rated voltage of 690V, which can cope with the harsh environment of medium and high voltage power systems. The excellent breaking capacity can reach 100kA, which can quickly and reliably cut off the short-circuit current to ensure system safety.

In terms of structural design, Schneider NW40HA-4000A-690V-3poles provides two installation methods for users to choose: drawer type or fixed type. The main terminal is cleverly designed and can be rotated to adapt to different on-site wiring requirements. Its front panel integrates a fault reset button, a switch operation button, an energy storage handle, and a main contact position indication window for easy human-computer interaction. The operation mode is flexible and supports manual, electric and remote control operation. In terms of safety protection, the circuit breaker has an insulation voltage of 1000V and an impulse withstand voltage of 12kV, which fully complies with the IEC 68-2 environmental test standard, has excellent performance, and has strong anti-interference ability.

FAQ

Does it support remote monitoring?
Yes, the Schneider NW40HA-4000A-690V-3poles can be equipped with an intelligent control unit, which can realize remote monitoring and data logging functions through the communication interface.

What is the difference with the MT series circuit breaker?
The NW series focuses more on marine and wind power-specific scenarios, while the Schneider NW40HA-4000A-690V-3poles covers a wider range of industrial applications and has a wider current range (630~6300A).

How to solve the tripping problem?
When encountering a tripping situation, the first thing to do is to check whether the load current exceeds the rated value. In addition, the detailed fault record can be viewed through the control unit to accurately locate whether it is an overload, short circuit or other specific reasons.
