Mars MARS-80316 Fused Disconnect 30 Amp 240 Vac

Product Description

The MARS MARS-80316 is a 30-amp fused disconnect designed for single-phase HVAC and refrigeration equipment operating at up to 240 VAC. It provides a local means of disconnecting power to condensing units, air handlers, and other outdoor or indoor equipment that requires a service disconnect at the unit. The switch is fusible, accepts standard cartridge fuses, and is rated for 50/60 Hz service. UL Listed construction confirms it meets recognized safety standards for electrical disconnect applications. Licensed electricians and HVAC technicians install this type of disconnect as required by NEC Article 440 for motor-driven refrigeration and air conditioning equipment.

The MARS-80316 is suited for residential and light commercial split-system air conditioners, heat pumps, and packaged units where a fused, two-pole disconnect is required at or near the equipment. It handles single-phase loads up to 30 amps at 240 VAC, making it appropriate for most residential condensing units in the 1.5- to 5-ton range. The compact footprint allows installation in standard disconnect enclosures or direct surface mounting near the equipment served.
