- 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.
- 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.
