Series FP, 3-phase relays

Product catalog summary

Overview: The C-mac® 3-phase monitoring relays series FP are designed for monitoring the quality of 3-phase supply voltages to protect connected electrical devices. They are suitable for both industrial and domestic installations, complying with EMC regulations.

Key Features:

Under-voltage, over-voltage, phase-sequence, and phase asymmetry monitoring with or without time-delay.
Single-pole relay output with a capacity of 8 A at 250 VAC.
DIN-rail housing dimensions: 35 mm wide, 45 mm front height.

Technical Specifications:

Supply Voltage: 3 x 220 VAC to 3 x 415 VAC +/- 25%.
Supply Frequency: 45 - 65 Hz.
Power Consumption: Approx. 1.5 W.
Operating Temperature: -20°C to +60°C.
Isolation Voltage: 4 kV between supply and relay output.
Humidity: 0-90% RH, non-condensing.

Indications:

Green LED: Supply ON and levels are OK (flashing indicates level error).
Red LED: Relay activated.

Compliance: The relays comply with EN 50 081-1 (emission), EN 50 082-2 (immunity), and EN 60 730-1 (safety) standards, and are CE approved.

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: Combines functions of FP30 and FP31.
FP35: Combined under- and over-voltage relay with fixed setpoints and adjustable reaction delay.

Functional Principles: The relays activate when monitored parameters are within limits and deactivate when outside limits. Time delay options are available depending on the module type.

Ordering Guide: The ordering guide provides options for customizing delay times, setpoints, and voltage ranges for each relay type.
