Lennox 93J31 Disconnect

The Lennox 93J31 Disconnect is a heavy-duty, 80 Amp 3-pole disconnect switch engineered for high-demand HVAC and industrial electrical systems. Also recognized by the alternate part number 93J3101, this front-operated non-fusible disconnect provides a decisive point of isolation for three-phase equipment, ensuring maintenance personnel can safely de-energize circuits during service or emergency shutdowns. Built to handle 600V AC applications, the rotary disconnect switch features a compact design suitable for both panel mounting and DIN-rail integration, making it a versatile choice for commercial HVAC electrical components.

For contractors in the field, the Lennox 80 amp disconnect is a direct OEM replacement for various Lennox models, including the GCS24, HP29, and LGA series. Its non-fusible architecture simplifies the installation process by removing the need for internal fuse management, while the front-mounted rotary operator provides clear, positive indication of the switch status. With a short circuit rating of 10kA when used with appropriate upstream protection, this industrial electrical disconnect is designed to meet rigorous safety codes and technical performance standards in demanding environments.

• 80 Amp High-Capacity: Designed to manage high-power electrical loads in commercial rooftop units and heavy-duty condenser systems.
• 3-Pole Configuration: Provides comprehensive power isolation for three-phase HVAC systems.
• Rotary Operator: Features a front-actuated rotary handle for ergonomic operation and clear visual confirmation of the "Off" position.
• Flexible Mounting: Engineering supports both flat panel surface mounting and standardized DIN-rail installation for varied control box layouts.
• OEM Compatibility: Identical to 93J3101, ensuring a drop-in fit without field modifications on compatible Lennox and ABB-specified equipment.

• Can this disconnect switch be used on 240V or 480V systems? Yes, the 93J31 is rated for up to 600V AC, making it suitable for standard 208/240V and 480V three-phase applications.
• Is the 93J31 interchangeable with the 93J3101? Yes, these part numbers are technically identical and serve as direct replacements for one another.
• Does this unit require fuses? No, this is a non-fusible disconnect designed for circuit isolation where separate overcurrent protection is already provided in the system.
