Lennox 99K30 Relay

Lennox 99K30 Relay

When you're dealing with three-phase motor protection in commercial rooftop units or heavy-duty HVAC systems, the Lennox 99K30 Overload Relay (also cataloged as 99K3001) is the standard for preventing catastrophic winding failure. This bimetallic thermal overload relay is engineered to monitor current draw and provide a precise 6.3-10 Amps adjustable trip range, ensuring your motors operate within safe electrical parameters. Designed for three-phase HVAC systems, it handles up to 690V and operates on both 50/60 Hz frequencies, making it a versatile drop-in for Lennox KCC, GCS16, and LCA series equipment.

For a technician in the field, the Class 10 trip rating means this relay reacts quickly to overcurrent conditions, interrupting the contactor coil circuit before heat can compromise the motor insulation. This Lennox OEM replacement part features a compact footprint (approximately 0.75” x 1.77” x 3.44”) for easy integration into existing control panels. By utilizing adjustable amperage settings, you can fine-tune the protection to match the specific Full Load Amps (FLA) of the motor you are servicing, significantly reducing nuisance trips while maintaining a high level of overcurrent protection and electrical safety.

Key Benefits
  • Precise Motor Safety: The adjustable 6.3-10 Amp trip range allows for exact calibration based on specific motor nameplate data.
  • Three-Phase Capability: Specifically compatible with 3-phase HVAC motors and industrial equipment up to 690V.
  • Class 10 Protection: Optimized for rapid response to electrical overload, preventing motor burnout and costly downtime.
  • OEM Compatibility: Guaranteed fit for Lennox KCC, GCS16, and LGA model commercial units.
  • Rugged Bimetallic Design: Built to withstand the high-cycle environments typical of commercial HVACR applications.
Common Questions

What equipment uses the Lennox 99K30 relay?
This relay is commonly found in Lennox commercial series, including the KCC180, KCC210, and KCC240 models, as well as GCS16-2553 and LGA092H4 units requiring 3-phase motor protection.

How do I set the trip current on this overload relay?
Use the adjustment dial on the front of the relay to align the pointer with the actual Full Load Amps (FLA) listed on your motor’s nameplate for accurate thermal protection.

Can the 99K30 handle 50Hz and 60Hz power supplies?
Yes, this thermal overload protector is rated for dual-frequency 50/60 Hz operation, supporting a wide range of industrial and commercial power configurations.
