York S1-TBK-371 Terminal Block
The York S1-TBK-371 Terminal Block is a professional-grade 3-pole electrical connector engineered for high-demand power distribution in commercial and industrial HVACR systems. Rated for 175A current capacity, this heavy-duty terminal block ensures secure phase connections and reliable integrity for large-scale equipment. Designed as a direct OEM replacement part, the S1-TBK-371 is built to handle the rigorous thermal and electrical loads common in chillers, air handlers, and rooftop units. Its three-pole configuration facilitates streamlined wiring for three-phase power applications, optimizing panel space while maintaining the mechanical stability required for high-vibration environments. Technicians can rely on the S1-TBK-371 for precise fitment and consistent conductivity, eliminating common failure points in power circuits. Whether you are performing a field repair or a system upgrade, this component provides the high-amperage performance necessary to maintain uptime and ensure the safe transfer of power across critical HVAC sub-systems without compromising circuit protection.
Key Benefits- 175A Rated Capacity: Handles high-amperage loads for commercial motor starters and heavy-duty power distribution.
- Secure 3-Pole Interface: Optimized for three-phase electrical systems, ensuring balanced power delivery and simplified terminal management.
- OEM Compatibility: Precision-engineered for seamless integration with York, Johnson Controls, and Unitary Products equipment.
- Industrial-Grade Durability: Withstands high thermal cycles and provides vibration-resistant connections to prevent voltage drops.
- Compact Footprint: Efficiently fits into standard control enclosures while providing ample clearance for high-gauge wiring.
What wire size is compatible with the 175A York terminal block?
The York S1-TBK-371 is designed to accept significant wire gauges typical for 175A circuits. Always verify the specific lug size on the unit to ensure your lead wire meets NEC requirements for the intended load.
Can the S1-TBK-371 be used in non-York equipment?
While designed as a York replacement part, its technical specifications allow it to function in any industrial control panel requiring a 3-pole, 175A terminal block, provided mounting dimensions and current ratings align.
Is this terminal block suitable for high-temperature environments?
Yes, this component is constructed with high-grade insulating materials specifically for the localized heat generated in high-amperage HVAC equipment compartments.
