residual current protection relay, VigiPacT RH21M, 30 mA or 300 mA, 220/240 VAC 50/60 Hz, DIN rail mounting

VigiPacT RH21M 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. The current sensitivity is selectable with 2 thresholds 30 mA and 300 mA. The time delay is instantaneous 0.06s. It requires a local manual reset after a fault clearance. The monitored distribution system voltage is up to 1000 VAC 50/60/400 Hz. 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.
