Lennox 21G87 Disconnect Switch
The Lennox 21G87 Disconnect Switch is a heavy-duty 150A 3P 600V Disconnect Switch engineered for high-capacity industrial and commercial HVACR applications. This three-phase safety switch provides essential electrical isolation for maintenance, featuring a robust steel enclosure and a copper-plated jaw mechanism to ensure reliable mechanical and electrical performance. Rated for 600V AC, the 21G87 is frequently utilized in Lennox LG/LC/LH and KG/KC/KD/KH series rooftop units (078 through 152 models), where it acts as the primary service disconnect for high-amperage blower motors and electric heat sections. The manual operating handle includes a visible position indicator for immediate status verification, while the UL Listed and CSA Certified construction ensures compliance with National Electrical Code (NEC) requirements for motor circuit disconnects. This non-fusible disconnect is designed to withstand the rigorous duty cycles of large-scale condenser units and air handlers, providing technicians with a reliable point of entry for troubleshooting and phase-isolated repairs in the field.
Key Benefits- 150 Amp High-Capacity Rating: Specifically built to handle the heavy inrush currents and continuous loads of large commercial HVAC equipment.
- 3-Pole Configuration: Complete isolation of all three electrical phases, providing a safe working environment for HVAC contractors.
- NEMA Rated Enclosure: Durable steel housing protects internal components from environment-specific wear in both indoor and outdoor installations.
- Direct OEM Compatibility: Ensures a precise fit and seamless integration with existing Lennox rooftop unit wiring make-up boxes.
- Visible Blade Design: Manual operation with clear indicator allows for rapid safety checks and lock-out/tag-out (LOTO) procedures.
Is the Lennox 21G87 suitable for inductive motor loads?
Yes, this 150A 600V disconnect is designed for high-inductive loads common in HVACR compressors and high-horsepower blower motors found in packaged units.
Can this switch be used with electric heat kits?
The 21G87 is primarily used when the total system amperage, including electric heat and blower motors, requires a 150A circuit protection or isolation point.
What wire size is recommended for this disconnect?
Always refer to the Lennox unit diagram and local codes; however, 150A disconnects typically accommodate large-gauge copper or aluminum conductors suitable for commercial power distribution.
