Ac miniature circuit breakers are applicable to the low-voltage terminal distribution. They are used for the short circuit and overload protection, control, isolation and DC system protection. Brand: Nader. Series: NDM1, NDB1, NDB2, NDM1T, NDB1C, NDB2T, NDM1F, NDB6.

Product Description

The Nader series circuit breakers are applicable to the low-voltage terminal distribution in the industry, civil buildings, energy, communication, infrastructure and other fields. They are used for the short circuit and overload protection, control, isolation and DC system protection.

 

NDM1-63 series:

AC230/AC240V (1P); AC400V (2P, 3P, 4P); DC80V (1P, 2P).

Tripping characteristics: Type B: 3ln~5ln, Type C: 5ln~10ln, Type D: 10ln~14ln.

50A and 63A products are not available for the NDM1-63 series Type D product. The breaking capacity of Type B and C products in the NDM1-63 series with the rated current of 1-40A is 6kA, while that of 50A, 63A and Type D product is 4.5kA. Only one type of protection accessories can be assembled on the right side; see the accessory for the specific model and parameters. A maximum of 3 OFs or SDs can be assembled on the left side of each product with the recommended number of assembly no more than 2. If the shunt release accessory is assembled on the right side, the residual current protection accessory or over-voltage/under-voltage accessory can't be assembled.

Protection class is IP20.
