Product details

The Schneider Electric RUMC31ED is a plug-in relay from the Harmony Electromechanical Relays range. It uses a 48 V DC coil and provides three changeover (3 C/O) contacts rated at 10 A at 250 V AC (IEC, NO) and 10 A at 28 V DC (IEC, NO). It carries UL 508, IEC 61810-1, and CSA C22.2 No 14 certifications, making it a straightforward pick for control panels requiring a general-purpose interface relay.

Ratings and operating margins

Operating voltage range is 38.4 to 52.8 V DC. Drop-out threshold is 0.1 Uc DC; coil resistance is 1800 Ω at 20 °C.
