Its heavy-duty construction minimizes voltage drop and heat generation at the terminals, maintaining the integrity of the unit's electrical bus. Whether you are configuring a multi-circuit residential furnace or a complex commercial rooftop unit (RTU), this 025-30891-000 HVAC part provides the exact OEM fit and conductivity required to prevent intermittent power loss and ensure the safe operation of the primary power circuit.

• OEM Compatibility: Specifically engineered for York S1-025-30891-000 applications, ensuring seamless integration with existing Square D breaker hardware.
• Enhanced Conductivity: Features high-grade terminal lugs to maintain a low-resistance connection for HVAC electrical distribution.
• Rugged Design: Built to withstand the thermal cycling and vibration common in outdoor condenser cabinets and air handlers.
• Streamlined Installation: The 4-lug configuration allows for rapid bridging of circuits, reducing labor time during field repairs.

Is this jumper bar compatible with other breaker brands?
This part is specifically cataloged as a Source 1 replacement for York equipment and is designed for use within specific Square D circuit breaker housings. Always verify the physical lug spacing and part numbers in the manufacturer’s technical manual before installation.

When should an HVAC jumper bar be replaced?
Replacement is necessary if you observe signs of arcing, pitting on the lug surfaces, or significant oxidation. Replacing the jumper bar during preventative maintenance helps prevent catastrophic failure of the distribution block.

Does this part work for both 208V and 240V systems?
Yes, the York S1-025-30891-000 is rated for standard HVACR voltage ranges, provided the total amperage does not exceed the rating of the circuit breaker and bus assembly it is installed on.
