VigiPacT RH99M 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 380/415VAC 50/60Hz. The operational supply voltage is 380/415VA C 50/60Hz. It is a type A earth-leakage protection class. The current sensitivity (IDn) is selectable with 9 thresholds from 30mA to 30A. The time delay (Dt) is selectable with 9 settings from instantaneous to 4.5s. The monitored distribution system voltage is up to 1000 VAC 50/60/400 Hz. It requires a local manual 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.
