RS PRO Voltage Monitoring Relay, 1-Phase or 3-Phase Systems

RS PRO Voltage Monitoring Relays are designed to protect electrical systems from voltage fluctuations. They are essential for safeguarding 1-phase or 3-phase systems by detecting phase loss, incorrect phase sequence, and controlling under/over voltage with adjustable limits.

Features and Benefits

Protection Against Under/Over Voltage: Ensures system stability by preventing damage from voltage irregularities

DIN Rail Mounting: Simplifies installation and integration into existing systems

230 VAC or 400 VAC Operating Voltage: Offers flexibility for various application requirements

Adjustable Delay Time: Provides customisable protection with off delay and on delay time adjustment between 0.1-20 seconds

IP20 Terminals and IP40 Front Panel: Enhances safety with robust protection against dust and accidental contact

1 X 8A CO or NO Relay Output: Ensures reliable switching for control applications

Applications

Protection of compressors

Electrical motors

Capacitors in compensation systems

Air conditioning and industrial cooling systems

Telecom base stations

Railway applications

Additional Information

Conforms to CE, cULus, DEKRA, IEC, IQNet, ISO EN 9000 standards

Screw terminal type for secure connections

Voltage sensing range of 150-300 V AC

Phase sensitivity for phase loss and sequence detection

Operating temperature range from -5 to 55 °C
