Functional Devices TR100VA004 Transformer

The Functional Devices TR100VA004 Transformer is a professional-grade power solution designed for contractors who need versatility and reliability in the field. This 100VA multi-tap transformer features a primary voltage range of 120/208/240/277/480 VAC, allowing you to carry one unit that adapts to almost any industrial or commercial power supply. The secondary output provides a steady 24 VAC at 96VA nominal, perfect for powering HVAC control circuits, building automation systems, and heavy-duty relay logic setups.

Built for durability and ease of installation, this unit includes a manual reset circuit breaker to protect downstream components from overcurrent conditions without the hassle of replacing fuses. The dual-threaded hub mount and foot mount options offer maximum flexibility when securing the unit to junction boxes or control panels. This Class 2 transformer is engineered to handle ambient temperatures from -30°F to 140°F, ensuring consistent performance in mechanical rooms and rooftop units.

Key Benefits for Technicians:

• Universal Primary Taps: Simplifies inventory by supporting 120V, 208V, 240V, 277V, and 480V primary inputs.
• Integrated Overcurrent Protection: The built-in manual reset breaker eliminates the need for external fusing and speeds up troubleshooting.
• Flexible Mounting: Equipped with dual 1/2 inch NPT hubs for easy attachment to standard electrical knockouts.
• High VA Capacity: Provides 100VA power rating (96VA nominal) to support multiple actuators, controllers, or high-draw contactors.
• Broad Operating Range: Rated for 50/60 Hz and extreme temperature environments common in industrial HVACR applications.
