AC voltage relay

Additional Details

We offer AC Voltage Relay or surface mountable relays for the voltage monitoring and protection of AC mains or generator systems. Alternatives are offered for safety against over and/or under voltage, for either single phase, 3 phases or neutral or 3 phase no neutral systems. This Microprocessor base comes with Modular design, 36mm width. Our AC Voltage Relay is ideal for Phase sequence monitoring, Phase failure monitoring and PTC protection.

Features

• Under and/or over AC voltage protection
• Single phase & neutral, 3 phase & neutral, 3 phase no neutral options
• Front facia "trip volts" adjuster sets relay de-energisation
• Front facia "diff volts" adjuster sets relay re-energisation (except PFR)
• DPDT relay outputs, rated 5 Amp @ 240 VAC
• LED indication of relay state
• DIN rail/surface mout case, screw terminals

Applications

Protection electromechanical device against voltage faults/li>

• Protection electromechanical device against reverse running
• Protection against a driving load (phase failure) Normal/emergency power supply switching.
• Phase sequence monitoring
• Phase failure monitoring
• PTC protection
