Coil is 24 V DC, drop-out threshold >= 0.1 Uc DC. Contacts are 3 C/O with AgNi material, rated 10 A at 277 V AC (UL/CSA) and 10 A at 250 V AC (NO) per IEC. That's enough for most panel interposing or output switching duties in control cabinets. Listed to IEC 61810-1, CSA C22.2 No 14, and UL 508. That covers the typical panel certification requirements in North America and Europe. The part carries a pollution degree 2 rating and an IP40 enclosure. Rated insulation voltage is 250 V IEC, 300 V CSA/UL.","metaTitle":"Schneider RUMC31BD Harmony Relay, 24 V DC, 3 C/O, 10 A","metaDescription":"Schneider Electric RUMC31BD, Harmony electromechanical plug-in relay. 24 V DC coil, 3 C/O contacts.
