Phase monitoring relay RP33 3-phase monitoring of phase-neutral voltages Built-in adjustable time-delay Separate adjustments for minimum and maximum limits 1-pole relay output 8 A / 250 V AC AC supply voltages up to 3 x 415 VAC Made in accordance with the and EMC regulations The C-mac® module type RP33 meters its own 3-phase supply voltage, and checks that all 3 phase-neutral voltages are within the adjusted limits, and in that case, the output relay is activated. If one or more of the voltages are over or under the limits for a period of time, which exceeds the set delay, the relay releases. The module can operate from 80 to 120% of the nominal supply voltage. NOTE: The unit can only be used at 3 phases plus neutral. If neutral is not available, monitoring module type RP30 must be used instead. EMC and safety regulations. Emmision: EN 50 081 - 1 Immunity: EN 50 082 - 2 Safety: EN 60 730 Approvals: The units are produced in accordance with the CE og low voltage regulations.
