Duties of Residual Current Protection Relay

It is to cut the circuit when there is an In fault current caused by an insulation fault and save the life of a person who may be exposed to that fault current.

Test of Residual Current Protection Relay

Checking and Reporting the mA Level of the Residual Current Protection Relay

Controlling and Reporting the ms Level of the Residual Current Protection Relay

1.Life Protection

According to IEC 60479-1, 30 mA value of leakage current is the limit value in terms of human health. Residual current protection switch provides safe protection by cutting the energy of the circuit instantly at values of 30mA (limit value) and above. Application areas:

1 Protected against direct contact

2 For protection against indirect contact

3 In all dangerous situations

2.Fire Protection

When the leakage current value reaches 300 mA, the fire hazard starts to occur due to the heat generated by the electric arc. The residual current protection switch provides a safe protection by cutting the energy of the circuit in terms of property and life safety at the 300 mA threshold value of the leakage current and above. Scope of application:

1 In places where there is a risk of fire

2 For protection against indirect contact
