Chint NL1-63 Type A RCCB 1P+N 3P+N 25A 40A 63A 30mA 100mA 300mA 6kA 10kA CHNT English version CE and UKCA certified Type A RCD

 

1. General 

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.

 

      Tripping sensitivity

      10mA – precision instrument leakage protection and bathroom use.

      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/500mA – protection against indirect contacts, as well as fire hazard.

 

      Tripping time

      Instantaneous – It ensures instantaneous tripping (without time-delay).

      Short time delay – It ensures any tripping at least 10ms.

      Selective – It ensures total discrimination with a nonselective RCD placed downstream.
