L7 Residual Current Circurit Breaker Elcb Rcd Description

Application

       Protection against the effects of earth leakage overload and short circuit currents.
      2P switching of ph & N, Phase only protected against overloads and short circuits.
      In commercial,industrial and domestic electrical distribution systems.
      Note:must mot be used as the sole means of providing protection against direct contact.
      The RCBO incorporates a residual current operated electromagnetic release which operates without any auxiliary source of suppl to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to In.The RCBO combined MCB&RCCB provides:
      Protection against indirect contact
      Complementary protection against direct contact
      Protection for the installation against in sulation faults.
