Description
Fuji Electric BRR19N-02S Earth Leakage Protective Relay 25mm 100mA 200/220V
The Fuji Electric BRR19N-02S is a current-operated earth leakage protective relay (漏電リレー) designed to detect ground fault leakage currents and trigger a protective circuit response. The relay operates by sensing residual current through a zero-phase current transformer (ZCT) with a 25mm aperture and trips when leakage reaches the 100mA threshold, opening the associated contactor or circuit breaker within 0.1 seconds. It is a compact, panel-mount relay unit from Fuji Electric Co., Ltd., manufactured in Japan.

Applications
Earth leakage protective relays like the BRR19N-02S are used in industrial electrical panels and motor control centers to provide ground fault protection for equipment and personnel. They work in conjunction with a separate zero-phase current transformer (ZCT) clipped around the load conductors: when the vector sum of line currents deviates from zero by the set threshold — indicating current leaking to ground — the relay energizes to trip a contactor or shunt-trip breaker and disconnect the load. The BRR19N series is commonly used in Japanese industrial machinery, factory automation systems, HVAC control panels, and general-purpose motor circuits operating at 200/220V. This type of relay is standard in Japanese electrical distribution practice and continues to be used in maintenance and replacement applications for legacy industrial equipment.
This Fuji Electric BRR19N-02S Earth Leakage Protective Relay has been inspected and is in good condition. It was pulled from a working environment where it was previously in use. The housing is clean with only minor signs of normal use; the green reset button, red test button, and leakage indicator are all present and intact.
