York S1-025-52314-000 Transformer

The York S1-025-52314-000 Transformer is a heavy-duty 150VA control transformer engineered for high-voltage industrial and commercial HVACR applications. Specifically designed for stability and reliability, this unit steps down 460V or 575V primary input to a standard 24V secondary output, providing a consistent power source for control circuits, contactors, and thermostats. This model includes an integrated circuit breaker for essential overcurrent protection, safeguarding sensitive low-voltage components against short circuits or thermal overloads. As the direct replacement for S1-025-49718-000, this authentic OEM part ensures proper fitment and performance in York, Luxaire, and Coleman equipment. For technicians servicing multi-voltage systems, the dual-primary voltage capability and 150VA power rating provide the necessary overhead for complex control logic and high-draw contactor coils without voltage drop. When replacing an aging or failed transformer, this direct-match spare eliminates the need for field modifications, maintaining the original equipment’s integrity and safety standards.

• Dual Primary Input: Supports both 460V and 575V configurations, offering versatility for different industrial electrical environments.
• High Power Capacity: The 150VA rating handles larger control loads and multiple solenoid operations simultaneously.
• Integrated Protection: Features a built-in circuit breaker to prevent damage to the secondary side from wiring faults or component failure.
• OEM Compatibility: This is the verified direct replacement transformer for part number S1-025-49718-000, ensuring identical mounting and electrical specs.

What is the primary application for the York S1-025-52314-000?
This transformer is primarily used in commercial air handlers, rooftop units (RTUs), and large-scale HVAC systems that run on 460V or 575V three-phase power and require 24V for the control system.

Does this unit replace the older S1-025-49718-000 model?
Yes, the S1-025-52314-000 is the official superseded part for the S1-025-49718-000 and is functionally identical with the same electrical footprint.

Why does this transformer include a built-in circuit breaker?
The circuit breaker provides localized protection for the 24V circuit. If a downstream component shorts or draws excessive current, the breaker trips on the transformer rather than blowing a fuse or damaging the windings.
