It switches with a 110 V DC coil and provides 2 C/O (changeover) contacts rated at 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 maximum rate under load suit it for moderate-speed control sequences in panels where the coil voltage is a fixed 110 VDC bus. The 250 V AC / 250 V DC maximum switching voltage covers common control voltages but limits use above that. Minimum switching requirements of 17 V and 10 mA mean it reliably switches dry-contact signals like PLC inputs, but below that threshold contact wetting may be unreliable. Dielectric strength of 1500 V AC between contacts and 1550 V AC between coil and contact, combined with a rated impulse withstand voltage of 4 kV, confirms isolation integrity for basic insulation in 250 V circuits. Electrical durability of 100,000 cycles resistive and mechanical durability of 5,000,000 cycles give a service life well beyond the typical panel maintenance interval for non-frequent switching. The B10d value of 100,000 cycles provides a safety reliability metric for functional safety applications where the relay is part of a safety-related control system. Certified to CSA C22.2 No. 14, UL 508, and EN/IEC 61810-1. The UL 508 listing covers industrial control equipment; CSA C22.2 No. 14 is the Canadian equivalent. EN/IEC 61810-1 is the core relay standard for electromechanical elementary relays. These certifications, together with the rated insulation voltage of 300 V CSA/UL and 250 V IEC, make the part acceptable for panels shipped into North American and European markets without additional agency review. The RT I protection category indicates the relay is a closed-type device with basic environmental protection. ## Integration notes The cylindrical pin shape fits standard 11-pin round relay sockets (e.g., Schneider RXZ series). Operating position is any position, so orientation within the panel is flexible. The lockable test button allows manual actuation for commissioning and troubleshooting without removing the relay. The status LED provides local visual indication of coil energization — useful for panel walk-downs and fault isolation. Coil resistance of 10000 Ohm at 20 °C +/- 10 % draws approximately 11 mA at nominal 110 V DC — a light load on the control supply. Drop-out voltage threshold of >= 0.1 Uc DC (>= 11 V) ensures positive de-energization even with residual voltage on the DC bus.","metaTitle":"RUMC2AB2FD Harmony Relay, 110 VDC, 2 C/O, 10 A, IP40","metaDescription":"RUMC2AB2FD plug-in relay, 110 VDC coil, 2 C/O contacts, 10 A rated, CSA/UL/EN certified.
