3SL71N-40 RCBOs

  • Overview

    1P+N in 2 modular width (36 mm);
    Up to 40 A;

  • Applications and functions

    Switching and isolation function
    Protection against overload and short-circuit currents
    Protection against the effects of sinusoidal alternating earth fault currents
    Protection against indirect contacts and additional protection against direct contacts.
    Protection against fire hazard caused by insulation faults

    Used in residential buildings

    Type AC: for which tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising.
    Type A: for which tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising.

    RCD with a rated residual current of maximum 30 mA are used for personnel, material and fire protection, as well as for protection against direct contact;
    RCD  with a rated residual current of maximum 300 mA are used as preventative fire protection in case of insulation faults;
    RCD with a rated residual current of 100 mA co-ordinated with the earth system according to the formula IΔn< 50/R, to provide protection again indirect contacts
     

  • Features

    The combination of an RCCB and a miniature circuit breaker in a compact design for personnel, fire and line protection.
    Electromagnetic type, voltage independent.
    The MCB part protects lines against overload and short circuits and is available in tripping characteristics B and C.
