HNB2L 6KA 30mA Remote Control Circuit Breaker Suppliers
HNB2L
HNB2L-63 Type Residual Current circuit breaker (RCCB)(without overcurrent protection)ensure electrical safety in homes and similar situations, such as offices and other buildings as well as for industrial applications by protecting electrical installations against leakage Current reach to 30mA. Once a fault is detected, the Residual Current circuit breaker automatically switches off the electrical circuit to prevent risk to the people. Warranting reliability and safety for people and assets.

Product Advantages
Operating mechanism is plastic structure, operating performance is more stable and reliable than metal structure. such as release force, mechanical life cycle.For environmental protection is better than metal type and also the type is new generation mechanism.
All screws are with the plastic cover seal the holes,lt’s move safety can not open the products in easy.
A Big sizes transparent signboard can help user make some special marks in the signboard area.
The very new tripping structure make more safety
Cambered cover and handle make the operation be more comfortable and appearance be more beautiful.
Protect the circuit under the condition of overload, and the handle is tripped and stopped at the middle position, so as to repair the circuit with fault quickly. The handle cannot be stopped at the position during manual operation.
lt has earthing fault, electric leakage and isolation and protection function.
It is equipped with finger-protection wiring terminal.
The shell and components are made of high flame resisting, high temperature resisting and impact resisting engineering plastic.
lf the current of earthing fault or electric leakage exceeds the stipulated value, the circuit will be cut off automatically.
The dynamic and wire pressure are independent and are not affected by external disturbance and voltage fluctuation.
