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 Function Control electric circuits. Protect people against indirect contacts and additional protection against direct contacts. Protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing, tertiary sector and industry. 1.2 Selection Detectable wave form Type B Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct residual currents, whether applied suddenly or increasing slowly. Tripping sensitivity 30mA - additional protection against direct contact. 100mA - co-ordinated with the earth system according to the formula IΔn＜50/R, to provide protection against indirect contacts; 300mA - protection against indirect contacts, as well as fire hazard. Tripping time Instantaneous It ensures instantaneous tripping (without time-delay). 1.3 Approvals and certificates CE, KEMA 1.4 Add-on devices AX-5 auxiliary contacts TC-1 terminal cover CATALOG NL210 Residual Current Operated Circuit Breaker without Over-current Protection PDF
1.1 Function Control electric circuits. Protect people against indirect contacts and additional protection against direct contacts. Protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing, tertiary sector and industry. 1.2 Selection Detectable wave form AC class Tripping is ensured for slowly increasing sinusoidal AC residual currents. A class Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly. S, G/SI class Tripping is ensured not only for sinusoidal AC residual currents but also for pulsed DC residual currents whether applied suddenly or increasing slowly. S, G/SI type with filters against spurious tripping caused by harmonics and transient surges. With the impact of 8/20us surge 3000A, this high immunity RCCB will still be in stable status.
