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.

1.1 Selection Rated residual operating current I∆n = 30 mA: additional protection in the case of direct contact. Tripping class AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase. Tripping curve B curve (3-5 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 (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current. 1.2 Approvals and certificates CATALOG NB3LEU Residual Current Operated Circuit Breaker with Over-current Protection PDF
