RH197P DIFF.RELAIS VIGIREX 220/240V

RH197P is a front panel mounting residual current protection relay. It protects against people direct or indirect contact, property fire hazards and motors. It measures the earth leakage current in an electrical installation via its associated toroid. It trips the associated circuit breaker when the set residual operation current is overrun. The operational supply voltage is from 220 VAC to 240 VAC 50/60Hz. The current sensitivity is selectable with 19 thresholds from 30 mA to 30 A. The time delay is selectable with 7 settings from instantaneous to 4.5s. The alarm is set by Dip switch at 50% of IDn. A switch make the selection between local manual reset or automatic reset after a fault clearance. The monitored distribution system voltage is up to 1000 VAC 50/60/400 Hz. It is installed on a front panel switchboard and the protection degree is IP40. It must be associated with a compatible Schneider Electric toroid.
