vl5-40-rcbo-constructionConstruction Features


  • 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
  • Standard: GB16917.1, IEC61008


  • Our products have the guarantee period of 36 calendar months,that is a high quality and reliability;
  • Our products have an excellent ratio between price and quality ,you can possess them by competitive price and high quality;
  • The fast and flexible production form aim at the customer require;
  • The deliveries exactly in accordance with customer orders
  • The fast transportation.
  • Adopt electromagnetic style release , can play a leak electricity and electric shock protecting role while breaking in zero Line.

Construction Features:

  • Measuring component and buckling component of products is located between enter line end and entrance line end ;
  • Movement characteristic of products can not be changed with outside mechanical tool ;
  • The operating organization has the free function to take off and buckle;
  • Operate part can not be taken down from the shell outer of products , the shell can not influence the operating organization to work , the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running.
