Schneider NW40HA-4000A-690V-3poles

As your professional supplier, the Schneider NW40HA-4000A-690V-3-phase equipment from Yueyang Tongtu can safely control a current of 4000 amperes. It serves as a solid safety barrier for your power distribution system, completely eliminating the risk of power outage for the entire factory due to main line failures.

Application scenario

The most common applications include the main incoming cabinets in large data centers, the main distribution cabinets in metallurgical factories, and the low-voltage side main switches of large chemical enterprises. In any situation where the current is extremely high, the requirement for continuous power supply is extremely high, frequent operation is necessary, or remote monitoring is needed, this Schneider NW40HA is definitely the main force. It is the "master valve" of the entire low-voltage power distribution system, controlling the power lifeline of the entire factory.

Product advantages

As a professional exporter of Schneider NW40HA-4000A-690V-3 pole circuit breaker, we offer products of original quality. Under high current conditions, this can pose a fatal danger. The products we provide will all undergo inspection before shipment. The products you receive are brand new and can be used by both new and old customers with peace of mind, without worrying about overheating accidents caused by poor contacts.

Structure

The contact system in our Schneider NW40HA-4000A-690V-3pole model is very sophisticated. It adopts a multi-plate parallel contact design and is equipped with a powerful arc extinguishing chamber. As you know, the electric arc generated during the large current disconnection is extremely terrifying. This arc extinguishing chamber can instantly elongate, cool down and extinguish the arc, ensuring that the contacts are not damaged. The internal mechanical linkage mechanism has been precisely calibrated to ensure that the contacts make a tight contact when closed and move smoothly when opened. The busbar connection terminals on the back or at the bottom are made very thick and can directly connect to the copper busbar. Its pull-out design is also very ingenious, allowing it to be conveniently removed from the fixed cabinet for maintenance. The structural design is very rigorous.
