Lennox ECBA25-7.5CB 7.5 kW Electric Heat Kit with Circuit Breaker 208-240V 1-Phase

The Lennox ECBA25-7.5CB Electric Heat Kit acts as the high-precision "heating brain" for smaller residential air handlers, providing essential supplemental heat during heat pump defrost cycles or as a primary emergency heat source. This 7.5 kW assembly is engineered specifically for Lennox CBA25UHV and CBA27UHE air handler series, featuring integrated sequencing to manage the electrical load safely. This staggered activation prevents sudden voltage drops in your home and ensures a consistent, comfortable rise in discharge air temperature, maintaining the efficiency and safety of your entire HVAC system.

Key Features

• Precision OEM Part Number: A direct factory-authorized match for ECBA25-7.5CB (Cat # 16Y41), ensuring the mounting plate and plug-and-play wiring harnesses align perfectly with Lennox air handlers.
• Integrated Circuit Breaker: Features a built-in heavy-duty circuit breaker for localized overcurrent protection, simplifying installation and meeting strict local building codes for high-wattage appliances.
• Silent Sequencing Technology: Utilizes high-grade internal sequencers to eliminate the loud "clunking" of heating stages, providing a gradual and quiet ramp-up of heat throughout the ductwork.
• Nickel-Chromium Elements: Constructed with premium Ni-Cr heating coils designed for rapid thermal transfer and high-temperature durability, ensuring years of reliable auxiliary heat performance.
• Thermal Safety Monitoring: Equipped with primary and secondary high-temperature limit switches that automatically cut power if airflow is restricted, protecting your equipment from overheating.

🛠️ HVAC Depot Pro Tip

Take a Picture First! Before sliding the new heat kit into the air handler cabinet, photograph the existing control board wiring and the low-voltage terminal block. 7.5 kW kits require specific amperage; ensure your field-supplied wire gauge (typically 8 AWG or 10 AWG depending on the breaker size and run length) matches the unit's nameplate requirements. Diagnostic Check: After installation, cycle the thermostat to "Emergency Heat." If the fan starts but the air remains cold, verify that the 24V "W" signal is reaching the sequencer terminals and that the integrated circuit breaker is fully engaged in the "ON" position.
