Description
The Arrow Hart MR-21-UCO is a compact midget relay designed for industrial control applications, offering reliable switching in electrical circuits. This model features a coil voltage rating of 440-480V AC at 50-60 Hz, making it suitable for high-voltage control systems in manufacturing, automation, and machinery. It provides single-pole and double-pole contact configurations with robust ratings for both AC and DC loads, ensuring versatility in handling motors, lights, and other equipment. Benefits include its small footprint for space-constrained panels, durable construction for long-term reliability, and easy installation with screw terminals. Compared to similar relays from competitors like Allen-Bradley or Siemens, the MR-21-UCO offers cost-effective performance with proven Arrow Hart quality, though it may lack modern features like LED indicators found in newer models. Drawbacks include potential obsolescence due to the brand's acquisition by Eaton, which could affect parts availability. Ideal for legacy systems or retrofits, this new surplus unit appears in excellent condition based on images, with no visible wear, scratches, or damage. Faceplate details confirm model MR-21-UCO, coil specs, and contact ratings; no serial number visible, but '7434' marking noted on base. No parent/child assets attached. Estimated market price range: $40-80 USD for new surplus; resources include Arrow Hart relay catalog (summary: outlines MR series specs, available via Eaton archives at https://www.eaton.com) and general relay installation guide (PDF summary: wiring diagrams and safety notes).
