Coil resistance is 470 Ohm at 20 °C ±10%, with a drop-out threshold ≥0.1 Uc DC and an operating voltage window of 19.2...26.4 V DC — the coil holds at 24 V nominal and drops out cleanly below about 2.4 V. Rated for 10 A at 250 V AC (resistive) and 12 A at 28 V DC per UL, with a maximum switching capacity of 2500 VA AC or 280 W DC. Minimum switching is 10 mA at 17 V — enough for dry-contact PLC inputs but not for gold-flashed signal-level circuits. Electrical durability is 100,000 cycles (resistive load) and mechanical durability is 5,000,000 cycles. The safety reliability figure B10d = 100,000 cycles applies when the utilisation coefficient is kept at 20 %. Listed as current production (active lifecycle stage). The part carries UL 508, CSA C22.2 No 14, and EN/IEC 61810-1 approvals — accepted in North American and IEC panels without additional qualification. Rated insulation voltage is 250 V (IEC) / 300 V (CSA/UL), with an impulse withstand voltage of 4 kV and dielectric strength of 1500 V AC between contacts. Plug-in relay with flat pins — mates with a standard 11-pin round or flat-pin socket (sold separately). Operating position is any position, so orientation in the panel is not constrained. Lockable test button allows manual actuation for commissioning without removing the relay. Status LED provides visual coil-energised indication — useful during panel checkout. Operating rate is ≤1200 cycles/hour under load; operating time is 20 ms. Shock resistance is 10 gn in operation, vibration resistance 3 gn at 10...150 Hz — suitable for most industrial machinery but not extreme mobile equipment.","metaTitle":"Schneider Electric RUMF3AB2BD Harmony Relay, 24 VDC, 3 C/O,","metaDescription":"Schneider Electric RUMF3AB2BD Harmony plug-in relay, 24 VDC coil, 3 C/O contacts, 10 A rated.
