Lennox 12L62 Heat Kit
The Lennox 12L62 (model ECBA25-10-3) is a 10kW electric heat kit designed for seamless integration with compatible Lennox air handlers and residential package units. Engineered for 208/240V three-phase applications, this auxiliary heater provides reliable supplemental heat or primary heating in milder climates. It features heavy-duty nickel-chromium heating elements for corrosion resistance and consistent thermal output. Rapid-response thermal limit protection is factory-installed to prevent overheating, ensuring the safety of the HVAC system during high-demand cycles. The assembly includes a plug-in wiring harness for accelerated field installation, reducing labor time during HVAC 3-phase heater change-outs or upgrades. This supplemental heat strip is specifically sized to meet the static pressure requirements of Lennox blower assemblies, maintaining airflow integrity while delivering a precise 34,100 BTU output. Field technicians should verify breaker sizing and conductor ampacity to ensure compliance with the Lennox 12L62 specifications and local electrical codes.
- Optimized Heating Performance: Delivers 10kW of reliable heat via high-grade nichrome heating coils for long-term durability.
- Standardized Integration: Features a plug-in wiring harness and pre-drilled brackets for a precise fit into the blower cabinet.
- Advanced Safety Controls: Includes an integrated automatic reset limit switch to protect the system against airflow restrictions or component failure.
- High-Voltage Efficiency: Designed specifically for 240V 3-phase electrical configurations commonly found in light commercial or specialized residential settings.
Common Technical Questions
Which Lennox air handlers are compatible with the 12L62?
This Lennox heat kit is primarily compatible with CBX25UHV, CBX27UH, and CBX32 series air handlers. Always verify the manufacturer's cabinet size (e.g., B, C, or D width) to ensure proper physical clearance for the heating element rack.
Does this unit require a separate power supply from the air handler?
Yes, in most 3-phase electric heater installations, you must size the circuit based on the Total Unit Ampacity (TUA) which accounts for both the blower motor and the 10kW heating load. Always consult the ECBA25-10-3 data plate for specific MCA and MOP values.
Can this be field-converted to a single-phase application?
No, the Lennox 12L62 is specifically wired and balanced for three-phase power. Attempting to convert the internal wiring for single-phase use will void the UL listing and lead to premature failure of the electric heat sequencers or elements.
