Schneider - 56172 EARTH LEAKAGE CURRENT SENSOR, PROTECTION RELAY, VIGIPACT RANGE, 0.03 TO 30 AMP, ADJUSTABLE

Earth Leakage Protection Relay, 0.03 to 30 Amp, Adjustable

VigiPacT RH99M is a DIN rail mounting residual current protection relay that measures the earth leakage current in an electrical installation via a toroid. The current sensor then trips the associated circuit breaker when the set residual operation current is exceeded, ensuring that industrial devices and personnel are protected from potentially dangerous situations.

The operational supply voltage is 110/130VAC 50/60Hz and the current sensitivity is selectable with 9 thresholds from 30 mA to 30 A.  Additionally, this earth leakage current sensor also features a time delay function that is selectable with 9 settings from instantaneous to 4.5 seconds.

This earth leakage current sensor requires a local manual reset after a fault clearance and the monitored distribution system voltage is up to 1000 VAC. Easy to mount, this earth leakage sensor is installed on a DIN-rail inside a switchboard with a protection degree of IP40. This current sensor is used in conjunction with a compatible Schneider Electric type A toroid or rectangular sensor.
