Functional Devices TR40VA013 Transformer 40VA Multi-Voltage 480/277/240/208 to 120VAC Circuit Breaker

The Functional Devices TR40VA013 is a versatile 40VA control transformer designed for HVAC and industrial control applications. This multi-tap transformer accepts four common primary voltages—480V, 277V, 240V, or 208V—and steps them down to a standard 120VAC secondary output, providing maximum flexibility for various installation requirements.

Key Features:

• 40VA power rating suitable for control circuits, relays, and automation systems
• Multiple primary voltage taps: 480/277/240/208VAC for universal compatibility
• 120VAC secondary output for standard control voltage
• Integrated circuit breaker protection for overcurrent safety
• Dual mounting options: foot mount or single threaded hub mount
• UL recognized Class 2 transformer for safe, code-compliant installations
• Compact design for space-constrained electrical panels and control boxes

This transformer is ideal for powering thermostats, control relays, contactors, actuators, and other low-voltage control devices in commercial and industrial HVAC systems. The built-in circuit breaker eliminates the need for external overcurrent protection, simplifying installation and reducing panel space requirements. The flexible mounting configuration allows for either traditional foot mounting or hub mounting directly into a knockout, adapting to various enclosure types.
