Short description of LV481000
VigiPacT RHUs 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. It can activate an alarm and a pre-alarm. The operational supply voltage is 110/130VAC 50/60Hz. It is a type A earth-leakage protection class. The current sensitivity is from 30mA to 30A. The time delay is adjustable from 0 to 4.5s. It is installed on a front panel switchboard and the protection degree is IP40. It must be associated with a compatible Schneider Electric type A toroid or rectangular sensor. It complies with IEC 60755, IEC 60947-2 annex M and IEC 60947-5-1 standards.
