Functional Devices TR100VA001 Transformer

The Functional Devices TR100VA001 is a commercial-grade 96VA class 2 transformer engineered for heavy-duty HVACR applications requiring a stable 24Vac secondary voltage from a 120Vac primary power supply. This unit features a single threaded hub mount and foot mounting options, providing versatility for junction box or panel installations. To ensure system reliability and protect downstream controls, it includes an integrated circuit breaker over current protection, which allows for a manual reset if a trip occurs. Designed for durability in demanding environments, this 120V to 24V step down transformer handles inductive loads efficiently, making it an ideal choice for multi-zone hydronic systems and large commercial HVAC direct digital controllers. By utilizing a high-efficiency transformer with circuit breaker, technicians can reduce diagnostic time and safeguard expensive control boards against overcurrent spikes and short circuits during commissioning or routine maintenance.

• 96VA power rating provides sufficient overhead for high-draw contactors, dampers, and sophisticated control systems.
• Integrated manual reset circuit breaker eliminates the downtime and cost associated with replacing blown fuses.
• Dual mounting configuration allows for secure foot mounting or convenient 1/2" threaded hub attachment to standard electrical knockouts.
• Maintains consistent 24Vac output to ensure optimal performance of sensitive 24V thermostats and building automation sensors.
• Compact footprint fits within standard enclosures while meeting Class 2 transformer safety standards for low-voltage equipment.

Can I use the TR100VA001 for multiple 24V zone valves?
Yes, the 96VA rating is specifically designed to handle the simultaneous inrush current of multiple zone valves or dampers that exceed the capacity of standard 40VA or 50VA units.

What happens if there is a short in the 24V wiring?
The built-in resettable circuit breaker will trip to protect the internal windings. Once the fault is cleared, the technician can manually reset the breaker to restore power.

Is this transformer suitable for outdoor rooftop unit (RTU) replacements?
When housed within a NEMA-rated enclosure or the existing equipment cabinet, the Functional Devices TR100VA001 is an excellent choice for RTU control upgrades and repairs.
