Product Description
- "VigiPacT RMH is a front panel mounting communicating residual current monitoring relay."
- "It monitor drops in electrical insulation due to ageing of cables or extensions in the installation."
- "It measures the earth leakage current in an electrical installation via its associated toroid."
- "A control signal is issued by the relay when the residual-current operating threshold is overrun."
- "It is used with a VigiPacT RM12T multiplexer, allowing connection of 12 measurement channels maximum."
- "The operational supply voltage is 220/240VAC 50/60Hz."
- "It is a type A earth-leakage protection class."
- "The current sensitivity (IDn) is adjustable from 30mA to 30A by channel."
- "The time delay (Dt) is adjustable from instantaneous to 4.5s by channel."
- "There is an automatic reset after a fault clearance."
- "The monitored distribution system voltage is up to 1000VAC 50/60/400Hz."
- "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."
Key Features
- "VigiPacT relays ensure coordination with ComPacT circuit breakers (switch off within 40ms)"
- "Continuous monitoring of the power supply, the relay/toroid link and internal electronics"
- "Reinforced insulation of VigiPacT relays (overvoltage category IV)"
- "Access to settings protected by a lead-sealable cover or password"
- RoHS and REACH compliant
