Device Component Descriptions

Details each functional part of the relay, including controls, indicators, and settings.

Adjustment of IΔn

Setting the residual current threshold (IΔn) for tripping.

Test Button Functionality

Button used to perform a functional test of the relay's operation.

Reset Button Operation

Button to reset the relay after it has tripped or encountered a fault.

Voltage Presence Indicator

Green LED that confirms the presence of a power supply to the device.

Tripping and Interruption Indicators

Red LED indicates relay trip or flashing red for connection interruption.
