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.
Features :
- When MCB normally open or trip because fault, the phase line and neutral line should keep disconnected status to avoid the electric hurt by electrified neutral line
- Full Protection Functions with overload and short-circuit protection. When connect or do breaking operation, you should connect the neutral line at first, then do breaking operation
- Connection is safety and reliable: use "Frame" connection structure
- Easily mounting: TH35 standard mounting rail
