NB1-63DC DC Miniature Circuit Breaker

1.1 Function Personnel and fire protection Cable and line protection against overload and short-circuits. 1.2 Selection I∆n ≤ 30 mA: additional protection in the case of direct contact. I∆n ≤300 mA: preventative fire protection in the case of ground fault currents. AC class – Tripping is ensured for sinusoidal,alternating currents, whether they be quickly applied or slowly increase. 1.3 Approvals and certificates CATALOG DZ158LE Residual Current Operated Circuit Breaker PDF

The NB2LE residual current operated circuit breakers are suitable for lines with AC 50/60Hz, rated voltage 240V, rated current up to 25A and for purposes of residual current protection, overload and short circuit protection. When any personal electric shock occurs or the circuit leakage current exceeds the predetermined value, the residual current operated circuit breaker can automatically cut off the power supply in a very short period of time, so that the safety of persons and electrical equipment can be protected. The residual current operated circuit breaker can be used for infrequent conversion of lines under normal conditions, and applied under occasions such as industrial, and commercial, high-rise buildings and residential houses.
