Circuit Breaker

Residual Current Circuit Breaker with Overcurrent Protection

VL5-40

Construction Features

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
Standard: GB16917.1, IEC61008

Advantage

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.
