RCBO NB310L/3N 3P+N C32 30mA A TYPE 6kA

NB310L Residual Current Operated Circuit Breaker with over-current protection (Magnetic). Personnel and fire protection: Cable and line protection against overload and short-circuits. Rated residual operating current 30mA: additional protection in the case of direct contact. Approvals and certificates CE/CB/KEMA.

A class tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly or slowly increase.

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