MARS U065NA1 UO65NA1 Disconnect Switch

The MARS U065NA1 is a professional-grade 60 Amp non-fused disconnect switch engineered for reliable circuit protection in residential and commercial HVACR applications. Designed with a rugged NEMA 3R metallic enclosure, this unit provides superior weather resistance for outdoor condenser and heat pump installations. The UO65NA1 disconnect switch features a unique 3-piece construction that significantly expands the internal mounting and wiring area, allowing for faster terminal connections and easier wire management in tight spaces.

This 240V AC disconnect is built for versatility, with terminal lugs rated for both 60°C and 75°C copper or aluminum wire. The pull-out head is reversible, allowing the technician to lock the unit in the "OFF" position for safe equipment servicing. With a 10HP motor rating and a compact 5" x 9" x 2-3/4" footprint, this metallic non-fused switch is the standard choice for contractors requiring a durable, code-compliant AC safety switch that handles high-current loads without the need for additional fusing.

• Streamlined Installation: The 3-piece chassis design provides clear access to the back of the box, simplifying mounting on uneven exterior surfaces.
• Extreme Durability: The NEMA 3R steel enclosure is finished with a corrosion-resistant coating to withstand harsh environmental conditions.
• Flexible Wiring: Straight-in, straight-out wiring layouts with multiple knockouts facilitate quick power runs for 60A outdoor disconnect setups.
• Universal Compatibility: Mechanical lugs accept a wide range of wire gauges, ensuring compatibility with standard branch circuit conductors.

• Is this unit suitable for use as service entrance equipment? No, this is a non-fused disconnect designed to serve as a local safety shut-off for downstream equipment like air conditioners and refrigeration units.
• Can I use aluminum conductors with these terminals? Yes, the MARS U065NA1 features terminals approved for both 60°C and 75°C wire, compatible with standard HVACR power feeds.
• How does the pull-out handle improve site safety? The handle can be removed entirely or reinserted in the "OFF" position, preventing accidental energization while a technician is performing maintenance on the system.
