1. First of all, determine the leakage protector is good or bad as follows:(1) press the test button to see if it can accurately, quickly and reliably action, if it can show that the leakage protector is good, if it can't show that the leakage protector is bad should be replaced in a timely manner.(

Leakage protector is commonly known as leakage switch, its use is valid for about 5-8 years, if it is often overloaded with or often tripped, installed in damp places dusty places will reduce the service life, for the family it is recommended that 5-8 years for a replacement.Removal and replacement

The reasons for tripping are mainly the following four points:①, there is a leakage of electricity in the circuit. The so-called circuit leakage, that is, the leakage protection switch under the mouth of the circuit connected to a location of the insulation resistance value does not meet the require

Reasons for excessive leakage protector current1.OverloadThe rated current of the leakage protector is determined, if the circuit load exceeds the rated current, it will cause the leakage protector current is too large, false action or inaction and other problems.2. Short circuitShort circuit is one

An RCBO or residual-current operated circuit breaker with overload protection combines the functions of an RCCB and an MCB in one device. RCCBs detect earth faults and trip the circuit, while MCBs protect against overcurrent and short-circuit faults. RCBOs incorporate both of these protection mechan
