It carries a 120 V AC coil and three changeover (3 C/O) contacts rated 10 A in AC-1/DC-1 duty per IEC, with a maximum switching capacity of 2500 VA AC or 280 W DC. The lockable test button and integral status LED simplify commissioning and troubleshooting on the panel. The 10 A AC-1/DC-1 rating (NO contacts) is the resistive load curve — the figure that governs most general-purpose switching in control panels. For the NC pole, the rating drops to 5 A AC-1/DC-1 per IEC, so factor that into any normally-closed circuit path. Minimum switching is 10 mA at 17 V, which means it can handle dry-contact signals from PLC outputs or low-level sensors without stiction. Dielectric strength is 1500 V AC between contacts and 1550 V AC between coil and contacts — adequate for 250 V insulation class per IEC 61810-1. Coil consumption is 2 to 3 VA at 60 Hz, and the drop-out threshold is ≥ 0.15 Uc AC — so the relay releases reliably when the control voltage falls below about 18 V AC. Operating time is 20 ms, and the maximum cycling rate under load is 1200 cycles/hour. Electrical durability is 100,000 cycles resistive; mechanical durability is 5,000,000 cycles. The B10d safety reliability figure is 100,000 cycles, relevant if the relay is used in a safety-related control circuit. This is a standard ice-cube-style plug-in relay with flat pins, fitting a matching socket (not included). The RUMF3AB2F7 is listed to UL 508, CSA C22.2 No 14, and EN/IEC 61810-1. The rated insulation voltage is 250 V per IEC, 300 V per UL/CSA. Contact material is silver-nickel (AgNi), suitable for general-purpose resistive and inductive loads within the rated limits.","metaTitle":"Schneider Electric RUMF3AB2F7 Harmony Relay, 120 V AC, 3 C/O","metaDescription":"Schneider Electric RUMF3AB2F7 plug-in relay, 120 V AC coil, 3 C/O contacts, 10 A rated.
