RS PRO Phase, Voltage Monitoring Relay, Three Phase, CO, 150 → 210, 240 → 300V ac, DIN Rail

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.

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

Protection of compressors
Electrical motors
Capacitors in compensation systems
Air conditioning and industrial cooling systems
Telecom base stations
Railway applications
