NXB-125 Miniature Circuit Breaker MCB Air Circuit Breakers Type C Disconnector AC230/400V 6kA
Overload Protection, Short Circuit Protection, Din Rail Mounting
High-quality raw materials, Industrial Grade，environmentally friendly, safe, reliable, and durable, small size, light weight, many varieties and complete specifications.
NXB-125 Miniature circuit breaker is mainly used for AC 50Hz, single pole 230V, two, three, four pole 400V; rated current 63A to 125A line, as the overload and short circuit protection of power lines. At the same time, it can also switch on and off electrical devices and lighting circuits infrequently under normal conditions.It can also be used as an isolating switch for disconnecting lines for line and equipment maintenance. But it is not suitable for protecting motors.
Compliance with standards: GB/T 14048.2, IEC60947-2 and CCC, CE certification.
