When Elcb Will Trip?

When an installation has two connections to Earth, a nearby high current lightning strike will cause a voltage gradient in the soil, presenting the ELCB sense coil with enough voltage to cause it to trip.

What is the tripping time of ELCB?

As the very name signifies, ELCB has the primary function of monitoring the health of insulation by measuring the extent of leakage through the used insulation. The user of ELCB sets a tolerable value of leakage current, mostly setting at 30 mA tripping current.

How do I know if ELCB is working?

Checking the health of the ELCB is simple and you can do it easily by pressing TEST Push Button Switch of ELCB. The test push-button will test whether the ELCB unit is working properly or not.
