ABB – RCBs

Description

Green Timer

Residual current operated circuit-breakers are amperometric protection devices which trip when the system leaks a significant current to earth.


They continuously calculate the vector sum of the single-phase or three-phase system line currents and, while the sum is equal to zero, they allow electricity to be supplied; supply is rapidly interrupted if the sum exceeds a value preset according to the sensitivity of the device.

Havells – ELCBs (RCCB)

Description

Green Timer

The flow of current through electrical facilities always involves risks. Poorly insulated equipment, faulty wires and incorrect use of an electrical device cause currents to flow through the wrong path (i.e., through the insulation) to the earth. This current is called 'Leakage Current'.

Earth Leakage is an electrical hazard and is responsible for electrical shocks and fire risk. Earth Leakage and its associated hazard can be prevented by residual current circuit breaker (RCCB), also popularly known as Earth Leakage Circuit Breaker (ELCB).


Range :
16A to 63A
30mA, 100mA, 300mA
