ABB Monitoring Relay, 380V AC Control Voltage Rating, 0 to 30s Adjustable Time Delay - CM-PSS Series - 1SVR730784R2300 CM-PSS.31S

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.

Features & Benefits

• 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

Applications

• Industrial automation
• HVAC systems
• Water treatment works

How do I adjust the time delay on this product?
