Description Place of Origin : China Brand Name : Chint Model Number : NL210 Type : Residual Current Poles Number : 2, 4 Rated Voltage : 240V/415V Rated Frequency : 50/60hz Chint original NL210 2P 4P 25A 40A 63A Type B RCCB 30mA 100mA 300mA 10kA 1P N 3P N CHNT e-mobility Charging station B Type RCD   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
