ABB Phase, Voltage Monitoring Relay, 3 Phase, DPDT, 342 → 418V ac, DIN Rail

Spot power faults as soon as they pop up with this monitoring relay from ABB. By tripping a circuit breaker if it senses an issue, it helps stop problems in their tracks to cut the risk of hardware damage. As the device checks for overvoltage, undervoltage and phase failure, it provides comprehensive fault detection to let you rest easy. Support for tool-free DIN rail mounting snaps the unit into place in no time. Thanks to the product's adjustable time delay between 0 and 30s, there's no need for expected overvoltage to grind your process to a halt.

• Compact dimensions of 103.7 (L) x 22.5 (W) x 85.6mm (H) easily fit into a small enclosure
• Screw-clamp terminals to stop disruption from movement
• Wide voltage monitoring range between 342 and 418V AC, so it works with many standard power sources
• Front-mounted LED indicators clearly show circuit status for quick spot checks

• Industrial automation
• HVAC systems
• Water treatment works

You can control this relay's time delay by turning the screw dial on its front plate, making it easy to adjust to fit your system.
