Functional Devices-RIB TR50VA008 Transformer

The Functional Devices RIB TR50VA008 is a professional-grade 50VA power transformer engineered for multi-tap versatility in commercial HVACR and building automation systems. Built to handle 480/277/240/208Vac primary voltage inputs, this unit provides a stable 120Vac secondary voltage output, essential for powering controllers, relays, and actuators. The integrated circuit breaker provides reliable over-current protection, eliminating the need for external secondary fusing and simplifying field troubleshooting. Field technicians will appreciate the dual threaded hub mount and foot mount options, which allow for secure installation directly onto electrical junction boxes or inside control panels. The rugged construction ensures long-term performance under continuous duty cycles. Whether you are retrofitting an older RTU or commissioning a new BAS network, this RIB transformer offers the multi-voltage flexibility required to match diverse site power requirements without carrying multiple SKUs on the service truck.

• Multi-Tap Primary: Supports 208V, 240V, 277V, and 480V inputs for universal job site compatibility.
• Manual Reset Breaker: Integrated protection prevents equipment damage from secondary shorts or overloads.
• Dual Hub Mounting: Simplifies conduit connections and secure 1/2-inch NPT mounting to standard enclosures.
• Sub-Panel Ready: Compact 50VA footprint fits efficiently into crowded control cabinets.

Is this transformer suitable for 120V to 24V step-down applications?
No, the TR50VA008 is specifically designed for high-voltage primary inputs (up to 480V) with a 120Vac secondary output. Always verify your secondary voltage requirements before installation.

What happens if the secondary circuit draws more than 50VA?
The integrated circuit breaker will trip to protect the windings. Once the fault is cleared, the breaker can be manually reset to restore power to the control circuit.

Can the TR50VA008 be mounted externally on a junction box?
Yes, the dual threaded hubs allow for secure external mounting while keeping the high-voltage connections safely enclosed within the box.
