RP33, 3-phase monitoring

Product catalog summary
Overview: The document describes the C-mac® Phase Monitoring Relay RP33, designed for monitoring phase-neutral voltages in a 3-phase system. It includes adjustable time-delay features and separate adjustments for minimum and maximum voltage limits.
Specifications:
  • 3-phase monitoring of phase-neutral voltages.
  • Built-in adjustable time-delay with a potentiometer scale from 0 to 10 seconds.
  • Separate adjustments for minimum (80-95%) and maximum (105-120%) voltage limits.
  • 1-pole relay output with a capacity of 8 A / 250 V AC.
  • Operates with AC supply voltages up to 3 x 415 VAC.
  • Complies with EMC and safety regulations, including EN 50 081-1, EN 50 082-2, and EN 60 730.
Technical Data:
  • Supply voltage options: 3 x 230 V, 3 x 380 V, 3 x 400 V, 3 x 415 V, all with a tolerance of +/- 20%.
  • Supply frequency range: 45-75 Hz.
  • Power consumption: 2.5 VA.
  • Operating temperature range: -20°C to +60°C.
  • Humidity tolerance: 0 - 90% RH, non-condensing.
  • Accuracy: Upper and lower limit adjustments have a 5% accuracy, and time-delay has a 20% accuracy.
  • Hysteresis: 1% factory set.
Indications:
  • Green LED indicates supply voltage is connected.
  • Red LED indicates the relay is active.
Materials and Construction:
  • Housing made of NORYL-SE-1, grey, self-extinguishing.
  • Housing bottom made of NORYL SE-1, GFN-2, black, self-extinguishing.
  • Terminals made of nickel-plated brass.
  • Weight: 190 g.
Usage Notes:
  • The unit is designed for use with 3 phases plus neutral. If neutral is not available, the RP30 module should be used instead.
Ordering Information:
  • RP33-1-3-230 for 3 x 230 V (phase-phase).
  • RP33-1-3-380 for 3 x 380 V (phase-phase).
  • RP33-1-3-400 for 3 x 400 V (phase-phase).
  • RP33-1-3-415 for 3 x 415 V (phase-phase).

RP33, 3-phase monitoring-1

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.
