- Description
The ABB CM-PVS.41S (SKU: 1SVR730794R3300) is a three-phase monitoring relay designed to protect industrial equipment from phase faults including phase loss, phase sequence errors, and voltage asymmetry across a wide input range of 300–500 V AC. Part of ABB's CM series, the CM-PVS.41S features a dual changeover (2 C/O) output contact, an adjustable time delay of 0.1 to 30 seconds, and a compact 30 mm wide housing suited for DIN rail installation in control panels and motor protection circuits.

Applications & Use Cases
- Motor protection against phase loss, phase sequence reversal, and voltage unbalance in three-phase systems
- Protection of pumps, compressors, and HVAC systems operating on 300–500 V AC three-phase networks
- Industrial automation control panels requiring phase integrity monitoring
- Building management systems and critical infrastructure where phase faults must be detected and isolated rapidly
- OEM machine builders integrating compact DIN-rail-mountable protection relays into motor starter assemblies
Frequently Asked Questions
- What faults does the CM-PVS.41S detect?
- The CM-PVS.41S monitors three-phase supplies for phase loss, incorrect phase sequence, and voltage outside the rated 300–500 V AC window, triggering its 2 C/O output contacts after the set time delay.
- What is the adjustable time delay range?
- The time delay is adjustable from 0.1 to 30 seconds, allowing coordination with downstream protective devices and preventing nuisance tripping during brief supply disturbances.
- Is the CM-PVS.41S suitable for DIN rail mounting?
- Yes. At 30 mm wide and compliant with IEC 60715, the CM-PVS.41S mounts directly onto standard 35 mm DIN rails.
- Which markets is this relay approved for?
- The CM-PVS.41S carries CE, UKCA, cULus (UL 508 / CSA C22.2 No.14), and CCC certifications, making it suitable for European, UK, North American, and Chinese markets.
