MARS 83915 Disconnect
The MARS 83915 Disconnect delivers a reliable 60A non-fused power isolation solution for residential and light commercial HVACR systems. Engineered for 240V single-phase applications, this unit incorporates an integrated surge protector to shield sensitive electronic components—such as ECM motors and control boards—from transient voltage spikes. The NEMA 3R weather-resistant enclosure is constructed from galvanized steel with a corrosion-resistant powder coat, ensuring durability in demanding outdoor environments. Designed with the contractor in mind, the side-open door provides unobstructed access to the internal cavity, while the pull-out handle features a patented finger-safe design to prevent accidental contact with live terminals during service. With a 10,000 Amp interrupt rating and UL listing, the MARS 83915 meets NEC requirements for line-of-sight disconnection, making it a standard choice for condenser and mini-split installations requiring robust electrical protection and simplified field wiring.
Key Benefits- Integrated Surge Protection: Built-in MARS 83910 surge module protects compressors and electronics from power surges without needing a separate enclosure.
- Contractor-Friendly Access: The side-hinged door stays open during wiring, providing more working room than traditional top-opening models.
- Enhanced Safety: Features a finger-safe pullout and external LED status indicators (Green/Red) to quickly verify surge protection functionality.
- Rugged Construction: NEMA 3R rated galvanized steel housing with UV-resistant finish stands up to harsh weather and direct sunlight.
- Simplified Installation: Unitized design with pre-stripped leads and multiple knockouts reduces labor time on the job site.
Does this unit require fuses?
No, this is a non-fused disconnect. Overcurrent protection must be provided by the upstream circuit breaker in the main service panel.
How do I know if the surge protection is still active?
The enclosure features external LED diagnostic lights. A green light indicates the system is protected, while a red light or no light signals the surge module has sacrificialized itself to protect the equipment and requires inspection.
What wire sizes are compatible with the terminals?
The lugs are designed to accept up to #6 AWG copper or aluminum conductors, suitable for standard 60-amp circuit requirements.
