Lennox 27A13 Heater
The Lennox 27A13 5KW ECB45-5CB-P Heater is an OEM electric heat kit designed to provide supplemental or auxiliary heating in compatible Lennox air handlers. Part of the ECB45 series, this Lennox 5KW heater kit operates on 208–240V single-phase, 60Hz electrical power and features a factory-installed 30-amp circuit breaker for overload and short-circuit protection.
Engineered for compatible Lennox CBK45 and CBA25 series air handlers, the heater uses helix-wound nichrome resistance elements positioned directly in the airflow for efficient heat transfer. Integrated automatic-reset temperature limit controls and supplemental thermal cutoff protection help prevent overheating during abnormal operating conditions.
The Lennox ECB45-5CB-P electric heater is factory-assembled with installed controls and wiring, including low-voltage plug-in connections for compatible air handlers. Rated at a nominal 5.0 kW, actual heating output varies with supply voltage.
Technicians should verify the air handler model, electrical specifications, airflow requirements, circuit protection, and manufacturer-approved installation instructions before ordering or installing this Lennox replacement heater kit.
