FUNCTION | Leakage relay is applicable to AC voltage up to 660V, frequency of 50Hz power distribution system. It is widely used to prevent equipment failure and electrical fire, and protect human from electric shock. |
SPECIFICATIONS | There are six parameters needed to specify the leakage relay 2. Dia. of CT through hole- Ф (mm) and relative max. rated current value (A) 3. Rated residual operating current and non-operating current (mA) 4. Response time (S) 5. Rated control capacity:220V/5A 6. Installation method: normal type—fixed mounting(H type); rail-type or fixed type( Z type); panel type mounting(M type) |
RANGE | 1. Rated voltage: 380V/660V 2. Dia of CT through hole- Ф (mm) and relative max. rated current value(A): 25/100, 45/200,75/400,100/630 3. Rated residual operating current and non-operating current is adjustable and customized 4. Quick type response time: ≤0.1s; Time delay type response time: 0.2-2S |
TESTING AND QUALITY | All Mingrui leakage relays are designed, rated, manufactured and tested in strict compliance with IEC60755-1983. Routine tests performed on each leakage relay are reclosing function test, leakage alarm function test and power frequency voltage-withstand test. Mingrui's internal quality system has been developed and certified under ISO 9001 quality system |
CONSTRUCTION | The whole set leakage relay includes zero-sequence current transformer, electronic circuit, test circuit and tripping relay. For shipping all units are crated for added protection. |
OPTIONS | • Customized bigger current ampere or through hole is acceptable. |
