Why Choose the Emas RR3VP02 Three-Phase Voltage Protection Relay?
The Emas RR3VP02 is a compact three-phase analogue voltage protection relay designed to monitor industrial electrical supplies and protect connected equipment against abnormal voltage conditions. As part of the Emas RR3 Series, it combines adjustable under-voltage and over-voltage thresholds with phase sequence and phase loss monitoring for dependable protection of three-phase machinery and control systems.
The RR3VP02 allows the low-voltage threshold to be adjusted from 150–210 V AC and the high-voltage threshold from 240–300 V AC. An adjustable 0.1–20 s delay-off period helps prevent unnecessary switching caused by brief supply disturbances, while a fixed 5 V hysteresis supports stable relay operation around the selected voltage thresholds.
Operating from a 230 V AC, 50/60 Hz supply, the RR3VP02 provides a 1CO changeover relay output rated at 10 A / 250 V AC for resistive loads. Its compact DIN rail mounted, fingerproof construction and IP20 protection make it straightforward to integrate into industrial electrical cabinets, motor control panels and automation systems.

Reliable Voltage Monitoring for Three-Phase Systems
Three-phase electrical equipment can be affected by under-voltage, over-voltage, incorrect phase sequence and phase loss. A voltage protection relay continuously monitors the incoming supply and changes the state of its output relay when conditions move outside the selected limits, allowing connected control equipment to disconnect or inhibit machinery before damaging operating conditions persist.
The Emas RR3VP02 combines adjustable 150–210 V AC under-voltage and 240–300 V AC over-voltage thresholds with phase sequence and phase loss monitoring. Its adjustable delay and 5 V hysteresis provide additional control over how the protection system responds to changing supply conditions.
Typical Applications
- Three-phase motor and machinery protection.
- Industrial pumps, fans and compressors.
- Conveyors and material handling systems.
- Packaging and production machinery.
- Phase sequence and phase loss monitoring.
- Industrial automation and electrical control panels.
