Lennox 21G88 Disconnect Switch

Lennox 21G88 Disconnect Switch

The Lennox 21G88 Disconnect Switch is a heavy-duty, 3-pole electrical safety component engineered for high-demand industrial and commercial HVACR applications. Rated for 600V 150Amp service, this unit provides a reliable manual breaking point to isolate 3-phase power during critical system maintenance or emergency repairs. Built with a rugged steel housing and a high-conductivity copper-alloy contact system, the 21G88 is designed to withstand the thermal stress and electrical loads of large-scale rooftop units and chillers. As a genuine OEM Lennox part, it ensures precise fitment and electrical synchronization with popular LGM series models (including LGM036, LGM048, and LGM060), maintaining the integrity of the original equipment's safety circuit according to NEC requirements.

Key Benefits:

  • Industrial-Grade Safety: Provides a secure manual disconnect for commercial HVAC systems, ensuring technician safety during high-voltage service.
  • 3-Pole Phase Control: Capable of simultaneously breaking all three electrical phases, ideal for 600V safety switch configurations in heavy machinery.
  • Durable Construction: The 150 amp disconnect features a reinforced steel enclosure that protects critical internal contacts from environmental debris.
  • OEM Compatibility: Specifically engineered as a direct replacement for Lennox 21G88, eliminating the need for field modifications and ensuring factory-spec performance.

Common Questions:

Is the 21G88 suitable for outdoor installations?
Yes, when mounted within its designated NEMA-rated enclosure, this manual disconnect switch is built to handle the rigors of commercial outdoor environments typical of large HVAC installations.

Can this switch be used for motor branch circuit protection?
The Lennox 21G88 is designed as a primary disconnect means and should be applied in accordance with local codes and the specific load requirements of your 150A 3-phase system.

Does this unit include the handle mechanism?
This is the internal replacement disconnect switch component; please verify if your specific application requires additional external linkage or handle operators for flange or through-the-door mounting.
