Leakage Relay
The MRD-RLJ leakage relay could work together with breaker, AC contactor, magnetic starter and other components of shunt release/no-voltage release to form an earth leakage protection system, thus eliminating the risk of earth leakage (caused by ground fault) and consequent electrical shock. What is more, it can also be equipped with buzzer and other acousto-optic devices so as to give alarms when earth leakage takes place.
Advantage
1. As a kind of earth leakage circuit breaker, our product is characterized by small size, easy installation, convenient operation, adjustable operating value and stable performance.
2. The protective relay realizes continuous monitoring, so any electric leakage caused by insulation aging or other reasons will be observed in time.
3. For variable frequency drive, this earth leakage protector exhibits strengthened anti-interference to high frequency, thus providing highly reliable performance.
4. The leakage relay is interchangeable with zero sequence current transformer, and its guide rail is DIN48×48mm.
Application
Our leakage relay is suitable for solidly grounded, low voltage power distribution systems with frequency of 50Hz and voltage up to 660VAC. According to the operating time, it can be classified into fast-speed relay and time-delay relay, and these two types can work together to protect main power line and branch power line.
Note: Larger current or hole size is available if requested.
