The MARS mars-80315 is a 60-amp non-fused disconnect switch designed for use in HVAC and related electrical service applications. A non-fused disconnect provides a manual means of isolating electrical equipment from its power source without incorporating an internal fuse element, relying on upstream overcurrent protection to safeguard the circuit. At 60 amps, this disconnect suits a wide range of residential and light commercial condensing units, air handlers, and similar equipment. Licensed electricians and HVAC technicians install this type of device per NEC requirements at or near the equipment being served.
This disconnect is appropriate for outdoor or indoor installations where a local means of lockout and isolation is required by code or by the equipment manufacturer. It is commonly installed adjacent to condensing units, heat pumps, and packaged rooftop systems where service personnel need a safe, visible means of de-energizing the unit before performing maintenance or repairs. The 60-amp rating accommodates the load requirements of many standard residential split-system and packaged HVAC units.
Designed as an OEM-style replacement or field-installed disconnect for residential and light commercial HVAC systems requiring a 60-amp non-fused disconnect. No specific model compatibility was provided in the product data.
Installation must be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the upstream circuit breaker before beginning installation. Mount the disconnect within sight of and within the required distance from the equipment it serves, as specified by NEC Article 440. Do not exceed the rated amperage of the disconnect when sizing for the connected load.
