3-phase monitoring relays series FP

  • Under-voltage monitoring with or without time-delay
  • Over-voltage monitoring with or without time-delay
  • Phase-sequence monitoring with or without time-delay
  • Phase asymmetry monitoring with or without time-delay + various combinations of these monitoring principles
  • Single-pole relay output 8 A - 250 VAC
  • Made in accordance with the CE and EMC regulations
     

The C-mac® 3-phase monitoring relays series FP are made particularly to meet the requirements for safe and cost-effective monitoring of the quality of the 3-phase supply voltages and to protect electrical devices connected to the mains supply.

The units are enclosed in a DIN-rail housing, 35 mm wide and front height 45 mm, which makes them very suitable in industrial installations as well as domestic switchboard panels.

All units are connected to the 3-phase supply voltage with or without neutral and have a 1-pole relay output.
The units are made in accordance with the EMC regulations for use in industrial environment.

The FP series consist of the following variants:

FP30: Combined under- and over voltage relay with fixed reaction delay and adjustable setpoint.

FP31: Phase sequence / phase asymmetry relay with fixed reaction delay and adjustable setpoint.

FP34: Combined phase sequence and under- and over voltage relay with fixed reaction delay and
adjustable setpoint.

FP35: Combined under- and over voltage relay with fixed setpoints and adjustable reaction delay.

The functional principle is the same for all units:
When the supply voltage is connected, and the monitored parameters are within the selected limits, the output relay is activated, and if one or more of the parameters are outside the limits, the relay will release. The relay function can be with or without time delay, dependent on the type of module.
