Its 24 V DC coil draws 1.4 W at 470 Ω, and the relay carries UL, CSA, and IEC 61810-1 certifications for panel acceptance. ## Selection vs RUMC3AB2E7 Compared to the RUMC3AB2E7, which switches 10 A at 750 VA AC / 84 W DC with a 15 mW minimum, the RUMC3GB2BD is the lower-current, lower-power sibling — its 3 A / 750 VA AC / 84 W DC rating suits signal-level and light control loads, while the RUMC3AB2E7 handles heavier contactor or motor-starter duty.","metaTitle":"Schneider RUMC3GB2BD Harmony Relay, 3 C/O, 24 V DC, 3 A, 750 VA","metaDescription":"Schneider RUMC3GB2BD Harmony RUM plug-in relay: 3 C/O contacts, 24 V DC coil, 3 A switching, 750 VA AC / 84 W DC max, 15 mW min, UL/CSA/IEC certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Standards":"EN/IEC 61810-1 CSA C22.2 No 14 UL 508","status LED":"With","Series name":"Universal","Control type":"Lockable test button","Load current":"10 A at 28 V DC 3 A at 250 V AC","Shape of pin":"Cylindrical","Operating rate":"<= 1200 cycles/hour under load","Operating time":"20 ms","Product weight":"0.086 kg","lifecycle_stage":"current","Pollution degree":"3","Range of product":"Harmony Relay","Shock resistance":"10 gn for in operation 10 gn for not operating","Contact operation":"Low level","Contacts material":"Gold plated bifurcated silver","Device short name":"RUM","Average resistance":"470 Ohm at 20 °C +/- 10 %","Compatibility code":"RUM","Operating position":"Any position","Dielectric strength":"1500 V AC between contacts 1550 V AC between coil and contact 1550 V AC between poles","Protection category":"RT I","Vibration resistance":"3 gn, amplitude = +/- 1 mm (f = 10...150 Hz)10 cycles in operation conforming to EN/IEC 60068-2-27 4 gn, amplitude = +/- 1 mm (f = 10...150 Hz)10 cycles not operating conforming to EN/IEC 60068-2-27","Electrical durability":"100000 cycles for resistive load","Mechanical durability":"5000000 cycles","IP degree of protection":"IP40 conforming to EN/IEC 60529","Safety reliability data":"B10d = 100000","Utilisation coefficient":"20 %","Average coil consumption":"1.4 W","Maximum switching voltage":"250 V AC conforming to IEC 250 V DC conforming to IEC","Minimum Switching Current":"3 mA","Minimum switching voltage":"5 V","Product or component type":"Plug-in relay","Drop-out voltage threshold":">= 0.1 Uc DC","Maximum switching capacity":"750 VA AC 84 W DC","Minimum switching capacity":"15 mW","[Uc] control circuit voltage":"24 V DC","Contacts type and composition":"3 C/O","[Ui] rated insulation voltage":"250 V conforming to IEC 300 V conforming to CSA 300 V conforming to UL","[Ie] rated operational current":"2 A AC-1/DC-1 (NO) conforming to IEC 3 A AC-1/DC-1 conforming to UL 1 A AC-1/DC-1 (NC) conforming to IEC","Rated operational voltage limits":"19.2...26.4 V DC","Ambient air temperature for storage":"-40...85 °C","Ambient air temperature for operation":"-40...55 °C","[Uimp] rated impulse withstand voltage":"4 kV","[Ithe] conventional enclosed thermal current":"3 A at -40...55 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.78","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/330e216a4debbae64eabaa1569127273.pdf","sourceUrl":"https://www.se.com/th/en/product/RUMC3GB2BD/universal-plugin-relay-harmony-rum-3-c-o-24-v-dc-3-a-with-led/","alternativesUrl":"https://aoctrl.com/api/mcp/products/RUMC3GB2BD/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/RUMC3GB2BD","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/RUMC3GB2BD when reusing this data.
