Functional Devices TR50VA008 Transformer 50VA Multi-Voltage 480/277/240/208V to 120V with Circuit Breaker

The Functional Devices TR50VA008 is a versatile 50VA step-down transformer designed for HVAC and control system applications. This transformer accepts multiple primary voltage inputs—480V, 277V, 240V, or 208V—and converts them to a standard 120VAC secondary output, making it ideal for a wide range of commercial and industrial installations.

Key Features:

• 50VA power capacity for control circuits and devices
• Multi-tap primary voltage: 480/277/240/208VAC for maximum installation flexibility
• Secondary output: 120VAC
• Integrated circuit breaker for overload protection and easy reset
• Dual mounting options: foot mount and threaded hub mount for versatile installation
• UL recognized components for safe, code-compliant installations
• Compact design for space-constrained applications

This transformer is commonly used to power thermostats, control relays, actuators, and other low-voltage HVAC control devices. The built-in circuit breaker eliminates the need for separate overcurrent protection, simplifying installation and reducing component costs. The dual mounting configuration allows for flexible installation on control panels, junction boxes, or equipment housings.
