NB4LE Residual Current Operated Circuit Breaker (Electronic)

1.1 Function Personnel and fire protection: Cable and line protection against overload and short-circuits.

1.2 Selection Rated residual operating current I∆n ＝ 30mA, additional protection in the case of direct contact. RCD Type Type A RCD Type A is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly or slowly increase. Tripping curve B curve (3 In-5 In) protection and control of the circuits against overloads and short-circuits; protection for people and big length cables in TN and IT systems. 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.

1.3 Approvals and certificates CE/CB
