Product Description:

NEX1-12 permanent magnet vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear for 12kV power system, as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. Since the circuit breaker is designed with a permanent magnet mechanism and a direct drive structure, it has excellent performance, and is especially suitable for places where frequent operations are performed or short-circuit currents are broken many times. The circuit breaker is equipped with a special propulsion mechanism to form a handcart unit.
