Reznor 103495 Transformer

The Reznor 103495 is a heavy-duty 40VA step-down transformer engineered specifically for Reznor unit heaters and commercial HVAC systems requiring a step-down from 480V primary to 24V secondary power. This OEM replacement part is critical for maintaining the control circuit's voltage stability, ensuring that thermostats, gas valves, and ignition modules receive consistent 24V power. Built for high-voltage industrial applications, it features a rugged construction that handles the thermal demands of consistent cycling within high-efficiency heating units. As a direct-fit component, it simplifies HVAC transformer replacement by aligning with existing mounting footprints and wiring configurations. Integrating this 480V to 24V transformer ensures system reliability and prevents control board failures caused by erratic voltage drops. For technicians servicing Reznor equipment, installing this OEM Reznor part is essential for maintaining the integrity of the Class 2 control circuit and ensuring long-term operational uptime in demanding environments.

• Direct OEM Compatibility: Precise fit for Reznor 480V heating units, eliminating the need for field modifications.
• Robust 40VA Rating: Provides ample power for modern control systems, including electronic ignition and multi-stage valves.
• High-Voltage Isolation: Safely reduces 480V primary current to safe 24V secondary levels for low-voltage control circuits.
• Efficient Heat Dissipation: Designed to operate within the high-ambient temperature zones of commercial gas-fired heaters.

• Can I use this to replace a 20VA transformer? Yes, the 40VA rating provides a higher power capacity, making it a suitable upgrade for 20VA or 30VA systems, provided the primary/secondary voltages match.
• Is this transformer fused? This model typically requires external circuit protection; always verify the integrated fuse link or secondary circuit breaker requirements per the unit's wiring diagram.
• What are the primary lead colors? Standard Reznor 480V configurations typically use specific color-coded leads, but technicians should always verify with a multimeter during HVAC troubleshooting.
