VigiPacT RHU is a communicating residual current device for front panel mounting. It protects against direct or indirect contact with people, fire hazards and motors. It measures the leakage current in an electrical installation through its associated toroidal transformer. It trips the associated circuit breaker when the set residual current is exceeded. It can trigger an alarm and a pre-alarm. The operating supply voltage is 220/240VAC 50/60Hz. It is a type A earth fault protection class. The current sensitivity is between 30 mA and 30 A. The time delay is adjustable from 0 to 4.5s. It is installed on a front panel and has an IP40 protection degree. It must be connected to a compatible Schneider Electric type A toroidal or rectangular sensor. It complies with IEC 60755, IEC 60947-2 Annex M and IEC 60947-5-1 standards. RUH is integrated into the Smart Panel architecture with Modbus communication.
