Lennox 47W02 - Class 2 Transformer, 75 VA, 480 VAC 50/60 Hz Primary, 24 VAC Secondary, 3.2 Amp Circuit Breaker
The Lennox 47W02 is a Class 2 step-down transformer engineered for safe and reliable voltage conversion in HVAC systems. With a 75 VA power capacity, it is capable of supporting higher current loads typically required in more robust heating and cooling equipment. Designed to convert high input voltage (480 VAC at 50/60 Hz) to a safe and stable 24 VAC output, it ensures smooth operation of low-voltage components such as control boards, thermostats, ignition modules, and relays.
This transformer comes equipped with a built-in 3.2 amp circuit breaker, offering critical overcurrent protection. In the event of a power surge or fault, the breaker trips to prevent damage to the transformer or other connected components. This self-resetting feature ensures added safety, reduces maintenance time, and minimizes system downtime.
Constructed to meet Class 2 NEC safety standards, the 47W02 is UL recognized and suitable for both retrofit and OEM applications. The transformer’s robust enclosure, high-quality windings, and reliable insulation allow it to perform in harsh commercial environments, including rooftop units, air handlers, and large-scale HVAC installations.
