Lennox 27A17 Heat Kit

The Lennox 27A17 is a high-performance 15kW heat kit engineered for seamless integration into compatible Lennox air handlers. As the direct replacement for 16Y44 (ECBA25-15CB), this unit features helix wound nichrome heating elements, providing instantaneous heat transfer and consistent discharge temperatures. Designed for 208/230V single-phase applications, it includes a 60-amp circuit breaker and a 25-amp circuit breaker for integrated over-current protection, simplifying field wiring by eliminating the need for a separate external disconnect. This OEM Lennox heat strip is built with heavy-gauge galvanized steel and utilizes a plug-in wiring harness for rapid installation in CBA25 and CBK45 series units. For contractors looking to maintain system efficiency during low-ambient conditions, the Lennox 15kW electric heater ensures reliable supplemental or emergency heat without compromising airflow static pressure.
