RUMC31P7 Schneider Electric – Harmony (Zelio) RUM Universal Plug-In Relay, 3 C/O, 10 A, 230 V AC Coil, 11-Pin Cylindrical
The Schneider Electric RUMC31P7 is a three-pole universal plug-in relay from the Harmony RUM range, formerly Zelio Relay RUM. It has three changeover contacts (3PDT) rated 10 A, a 230 V AC 50/60 Hz coil and cylindrical 11-pin connection. Three independent changeover contacts let one relay switch a three-phase signal or handle several control functions at once, such as running a load, sending feedback to a PLC and lighting an indicator. A lockable test button allows the contacts to be checked during commissioning without energising the coil.
