The NKM2E series is moulded case circuit breaker.It has six different rated current models, suitable for various application scenarios, which are 125A, 250A, 400A, 630A, 800A, and 1250A. Among these, 125A, 250A, 400A, 630A, and 800A have 3P and 4P, while 1250A has 3P.The NKM2E series uses electronic components and microprocessors to monitor current and achieve circuit protection, offering higher accuracy and programmability for more complex circuit protection requirements.
Optional cooperation: The NKM2E electronic molded case circuit breaker has a three-stage protection function, and the circuit breaker with category B can selectively cooperate with other short-circuit protection devices connected in the same circuit under short-circuit conditions. Three stage protection action current and action time selection: Users can set and adjust the release according to the load current requirements. Self powered: The electronic release is powered by the circuit breaker itself, and the current signal and working power of the release come from the current transformer installed inside the circuit breaker. With "pre alarm" indication: When the actual operating current flowing through the circuit breaker reaches or exceeds the pre alarm action current lro, the "pre alarm" LED on the circuit breaker cover indicates yellow. With overload indication: When the load current exceeds the overload long delay action current, the LED on the circuit breaker cover indicates in red. High current instantaneous tripping function: When the circuit breaker is closed or in operation, when encountering a short circuit high current (≥ 20lnm), the circuit breaker is directly tripped by an electromagnetic tripping mechanism.
