Earth leakage mini circuit breaker

Application:

The ELCB is applied to the circuit of AC 50Hz with rated voltage up to 400V, rated current up to 50A, power supply neutral point earthing. It's mainly used to protect person from getting an electric shock and protect the building′s circuit devices from over current, it also can protect the earthing fault.

The ELCB is according with IEC61009-1:1991, GB16917.1-1997 standard.

Normal working condition and installation condition:

1. The maximum ambient temperature should be -5°C≤T≤40°C,average temperature should be ≤35°C

 at 24h

2.The altitude of installation place should not exceed 2000m.

3. The relative humidity should not exceed 50% at 40°C, it permits higher relative humidity when at a higher temperature, the average maximum relative humidity should not exceed 90% at maximum humidity month, and this month′s average minimum temperature does not exceed +25°C, and should take consideration of the condensation on the product′s surface for temperature change.

4. Pollution grade: 2

5. Installation type: 1,2

6. The external magnetic field of installation place should not exceed 5 times of earth magnetic field.

7. The mini circuit breaker is installed by standard mounting rail.

8. The mini circuit breaker is upright installation, knob upwards is switch on position

9. The installation place should be without obviously impact and libration.
