Product Description:

NEX1-12 indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear for 12kV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprises. heavy load and frequent operation. The occasion of breaking short-circuit current several times. The product adopts a new type of circuit breaker operating mechanism. The primary part of NEX1-12 can adopt international brand solid-sealed poles, and the vacuum interrupter and the main conductive circuit parts are solid-sealed as a whole to protect the interrupter from collisions, dust and condensation. The influence of dew, the environmental adaptability is large, the operation and maintenance costs are greatly reduced, and the primary part of the product is truly maintenance-free, and the operating mechanism is less maintained; the operating mechanism and the circuit breaker body are designed in one piece, which has been verified by type tests and has E2 level Electrical life, M2 mechanical life.
