Trane 15 kW Electric Heat Kit (50000-55000 BTU) MAYHTR1A15BKRB | Heat Strip with Built-in Breaker

When upgrading or replacing the auxiliary heating element in a residential split system, the Trane 15 kW Electric Heat Kit MAYHTR1A15BKRB provides critical supplemental warming. This factory-authorized internal heat strip slides directly into compatible indoor air handler cabinets. It utilizes the system’s primary blower fan to distribute emergency backup heat when an outdoor heat pump or central AC unit cannot keep up with extreme sub-zero winter drops.

Unlike base-model heat strips that require separate external electrical disconnect boxes, this premium 15 kW kit features a factory-integrated circuit breaker block. This built-in safety architecture handles up to a 60-amp max overcurrent protection profile, ensuring full compliance with local residential electrical codes while drastically reducing on-site installation labor and wiring complexity.

Features of Trane 15 kW Electric Heat Kit (MAYHTR1A15BKRB) 

• Integrated Circuit Breaker Disconnect: Eliminates the cost and wall space required for an external breaker box by building the safety disconnect toggle directly onto the face of the heat kit.
• Direct Cabinet Fitment: Sized with a compact 6-pound physical frame to slide smoothly into factory air handler knockouts without requiring sheet metal alterations or custom brackets.
• Emergency & Auxiliary Heat Stages: Provides up to 55,000 BTUs of staging warmth, serving as the essential secondary heat source during outdoor heat pump defrost cycles.
• Heavy-Duty Open Element Design: Constructed with high-grade nickel-chromium resistance wire and heavy-duty insulators to deliver near-instant heat transfer without structural popping sounds.
• Streamlined Wiring Interface: Features a plug-and-play wiring harness designed to mate instantly with the control board inside your indoor air handler.
