Chint NL210 Type B Residual Current Circuit Breaker, without over-current protection

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
      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
