MARS U035F2 UO35F2 Disconnect

The MARS U035F2 Fused Disconnect is a heavy-duty 30 Amp metallic disconnect switch designed for 120/240V single-phase HVACR applications. Built with a rugged NEMA 3R rainproof enclosure, this AC disconnect switch provides essential overcurrent protection for condensers, heat pumps, and refrigeration units. The 3-piece construction is a major plus for field work, completely opening up the mounting and wiring areas to simplify pulls and terminations. Featuring straight-in, straight-out wiring, this 30A fusible disconnect significantly reduces cabinet clutter and installation time on the job site.

Engineered for maximum flexibility, the MARS U035F2 terminals are UL-approved for use with both 60°C and 75°C copper or aluminum wire, accommodating a wide range of field requirements. The puller is designed for safety, allowing it to be removed or re-installed in the "OFF" position during equipment maintenance. This fused pull-out disconnect is rated for up to 3 HP at 240V, making it a reliable standard for residential and light commercial A/C unit installation where a code-required local safety switch is necessary.
