Description
The Trane TRR02027 Fused Transformer is a control power transformer used to convert high-voltage supply into low-voltage control power for system operation in HVAC systems. It steps down 460V primary input to a 24V secondary output with a 50VA capacity providing stable power for thermostats relays contactors, and control boards. The built-in use protection safeguards downstream components from electrical faults or overload conditions. Mounted inside air handlers, rooftop units, and control panels, it ensures safe and reliable operation of low-voltage control circuits across commercial and industrial equipment applications.
