Lennox 12R60 Heat Kit
The Lennox 12R60 (model ECB25-5CB-P or ECB29-5CB-P) is a high-performance 5kW electric heat kit designed for seamless field installation in compatible Lennox air handlers. Operating on 208/240V single-phase power, this auxiliary heating component provides a steady 17,100 BTUH capacity, making it an essential addition for heat pump systems requiring supplemental warmth during peak winter conditions. This OEM Lennox heat kit features helix-wound nichrome heating elements, which are positioned directly in the air stream to ensure instantaneous heat transfer and consistent discharge temperatures. For residential and light commercial contractors, the factory-installed 30-amp circuit breaker serves as a necessary disconnect, simplifying the electrical rough-in and ensuring compliance with local codes. Built for long-term reliability in demanding HVACR environments, the unit includes automatic reset limit controls and supplemental thermal cutoffs to prevent overheating, ensuring the Lennox 12R60 Heat Kit maintains optimal airflow and system integrity throughout the heating season.
Key Benefits- Direct Heat Transfer: Exposed nichrome elements provide immediate thermal response and improved energy efficiency within the air handler cabinet.
- Integrated Safety: Includes a 30A circuit breaker for overcurrent protection, often eliminating the need for a separate field-installed disconnect.
- Broad Compatibility: Engineered for use with Lennox CBX25UH, CB28UH, CBX27UH, and CBX32M series air handlers.
- Reliable Construction: Features high-grade materials and ETL listing for stable operation in high-static applications.
