NBH8LE Residual Current Operated Circuit Breaker with over-current protection (Electronic)

1.1 Function

Personnel and fire protection

Cable and line protection against overload and short-circuits.

1.2 Selection

I∆n = 10mA, 30mA: additional protection in the case of direct contact.

C curve (5-10 In) protection and control of the circuitsagainst overloads and short-circuits;          protection forresistive and inductive loads with low inrush current.

AC class – Tripping is ensured for sinusoidal,alternating currents, whether they be quickly          appliedor slowly increase.
