FAQs
The CM-PVS.31P is designed for easy DIN-rail installation using TH35-15 or TH35-7.5 rails. It features screwless push-in terminals for fast wiring and a wire-stripping length of 8 mm. Use flexible or rigid conductors up to 1.5 mm2 per terminal, and ensure the device is securely snapped onto the rail to withstand vibration in industrial environments.
Measuring range is 160–300 V AC (L–L) with a rated control voltage of the same range. Output consists of 2 SPDT contacts. I_e ratings are 4 A AC-12 and 3 A AC-15 at 230 V, plus 4 A DC-12 and 2 A DC-13. For safe operation, use the specified minimum switching capacity of 10 mA at 24 V and observe the device’s 6 kV/4 kV impulse withstand values.
Yes. The relay provides phase failure detection, phase sequence monitoring, and over/undervoltage monitoring, with configurable thresholds and an ON/OFF tripping delay up to 30 seconds. This makes it ideal for motor protection, ensured start-up sequencing, and reliable power-supply supervision in automation panels.
The CM-PVS.31P carries CE and UKCA conformity, UL/CSA listings, CCC declarations, and additional certificates such as CQC and DNV GL where applicable. These certifications support global deployments and simplify regulatory compliance during audits and supplier assessments.
With Easy Connect technology and screwless terminals, installation time is reduced and wiring errors are minimized, delivering lower commissioning costs. Long electrical/mechanical durability (AC-12 100,000 cycles; 30,000,000 mechanical cycles) reduces maintenance frequency, extending mean time between failures and lowering total cost of ownership in high-demand automation environments.
