Nader NDB2ZB series MCB is specially developed for the special requirements of DC circuit breakers in the DC power supply system of power engineering. It has overload long delay, short-circuit short delay and short-circuit transient protection functions. It can be used in the DC power distribution system with rated working current below 63A, and can realize full selective protection with the lower circuit breaker, so as to ensure that the system can effectively avoid the malfunction of the upper circuit breaker caused by the lower short-circuit current, and ensure the safe and reliable operation of the system to the maximum extent.
Nader NDB1-63 series MCB is mainly used for short-circuit protection, overload protection and isolation of terminal power distribution system with AC rated working voltage of 230V to 415V, DC rated working voltage of 60V to 80V, rated frequency of 50Hz / 60Hz, rated working current of 1A to 63A, pole number of 1P, 1P + N, 2P, 3P, 3P + N and 4P. It is widely used in low voltage terminal power distribution in industry, civil buildings, energy, communications and infrastructure.
