It carries a 110 V DC coil and two changeover (2 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 20 ms operating time and ≤1200 cycles/hour under load suit it for moderate-speed sequencing and interposing relay applications. The 10 A rated operational current at AC-1/DC-1 (NO contacts) defines the resistive load it can handle continuously. For inductive or motor loads, derate per the utilisation coefficient of 20 % — that means the relay is intended for light-duty switching, not heavy motor starts. The minimum switching capacity of 170 mW and minimum switching voltage of 17 V mean it can reliably switch low-level signals like PLC outputs or small pilot lamps, but the 10 mA minimum switching current sets a floor below which contact wetting may not occur. The 2 C/O contact arrangement gives two independent form-C sets, each rated 10 A (NO) and 5 A (NC) per IEC. The NC side derates to 5 A — factor that into your circuit if you need normally-closed paths at full current. Dielectric strength of 1500 V AC between contacts and 1550 V AC between coil and contact gives confidence for isolation in 250 V circuits. The 4 kV rated impulse withstand voltage (Uimp) supports surge protection in typical industrial installations. The relay is certified to EN/IEC 61810-1 (electromechanical elementary relays), CSA C22.2 No 14 (industrial control equipment), and UL 508 (industrial control panels). These cover the major North American and European regulatory jurisdictions. The AgNi contacts are standard for general-purpose switching — no cadmium, which simplifies RoHS/REACH documentation. Plug-in relay with flat pins — mounts into a socket (sold separately). The lockable test button allows manual actuation for commissioning. The status LED gives visual confirmation of coil energisation.","metaTitle":"Schneider Electric RUMF2AB2FD Harmony Relay, 110 VDC, 2 C/O,","metaDescription":"Schneider Electric RUMF2AB2FD Harmony plug-in relay, 110 VDC coil, 2 C/O contacts, 10 A rated, UL/CSA/CE.
