VigiPacT RH197M is a DIN rail 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 220/240VAC 50/60Hz. It is a type A earth-leakage protection class. The current sensitivity is (IDn) selectable with 19 thresholds from 30mA to 30A. The time delay (Dt) is selectable with 7 settings from instantaneous to 4.5s. The alarm is set by Dip switch at 50% or 100% 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 1000VAC 50/60/400Hz. It is installed on a DIN-rail inside a switchboard and the protection degree is IP40. It must be associated with a compatible Schneider Electric type A toroid or rectangular sensor.
