Functional Devices TR50VA015 Transformer

The Functional Devices TR50VA015 is a versatile multi-tap control transformer engineered for reliable 24Vac secondary power in demanding commercial and industrial HVACR applications. This 50VA class 2 transformer features primary voltage taps for 120, 208, 240, 277, and 480Vac, making it a critical stock item for technicians servicing diverse electrical environments. Built for durability and safety, it includes an integrated circuit breaker for overcurrent protection, eliminating the need for external fusing on the secondary circuit. The dual mounting configuration—utilizing both a foot mount and a single threaded hub—allows for seamless installation inside electrical cabinets or directly onto 4x4 junction boxes. Whether you are powering building automation controllers, contactor coils, or 24V actuators, the TR50VA015 provides stable voltage regulation and high-efficiency performance for low voltage control circuits.

Key Benefits

• Universal Primary Taps: Accommodates 120/208/240/277/480Vac inputs for maximum field flexibility.
• Integrated Protection: Manual reset circuit breaker protects the secondary windings from shorts and overloads.
• Flexible Housing: Includes a threaded hub mount and foot mount for various enclosure types.
• High VA Rating: Delivers a consistent 50VA output, suitable for multiple 24V peripheral devices.
• Rugged Construction: Designed by Functional Devices (RIB) to meet stringent industrial standards for continuous duty.

Common Questions

Can this transformer be used for multi-load 24V circuits?
Yes, as long as the total simultaneous draw of your actuators, relays, or controllers does not exceed the 50VA (approx. 2.08 Amps) rating of the secondary side.

How do I handle the unused primary wire leads?
Always cap off unused primary voltage taps with wire nuts or heat shrink to prevent accidental shorting against the enclosure or other live components.

Is this transformer suitable for outdoor installations?
The TR50VA015 should be installed within a NEMA-rated enclosure or a protected electrical junction box to shield the lead wires and circuit breaker from environmental contaminants.
