SCHNEIDER ELECTRIC - SNR56505 Erdschlussrelais RH197p, 0,03-30A, 0-4,5 - 56505

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. Ittrips the associated circuit breaker when the set residual operation current is overrun. The operational supply voltage is from 30VDC to 130VDC, or 48VAC 50/60Hz. The current sensitivity is selectable with 19 thresholds from 30 mA to 30 A. The time delayis 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.
