York S1-FRNR70 Fuse
The York S1-FRNR70 Fuse is a critical industrial-grade protection component engineered for high-demand HVACR systems. This 70A Fusetron Buss Fuse features a dual-element time-delay design, which is essential for handling the high inrush currents often encountered in commercial motor starts and compressor cycling without nuisance tripping. Rated for 250V AC, this Class RK5 fuse provides a high interrupt rating of up to 200kA, ensuring robust short-circuit and overcurrent protection for sensitive control panels and distribution equipment.
Built as a genuine Source1 OEM replacement part, the S1-FRNR70 ensures exact mechanical fit and electrical compatibility with York, Luxaire, and Coleman equipment. The blade terminal configuration and fiberglass cartridge construction are designed for durability in high-temperature environments. By utilizing this current-limiting fuse, technicians can maintain the selective coordination of their electrical systems, effectively isolating faults to a single branch and preventing wider system downtime. Its performance characteristics meet UL 248-12 standards, making it the preferred choice for contractors maintaining industrial HVAC electrical systems requiring reliable circuit safeguarding.
Key Benefits- High Interrupting Rating: Rated for up to 200,000 Amps to protect against catastrophic short-circuit events.
- Dual-Element Construction: Provides superior time-delay to accommodate temporary motor overloads and surges.
- OEM Compatibility: Exact replacement for York S1-FRNR70 ensures proper physical dimensions and terminal alignment.
- Current-Limiting Design: Rapidly clears faults to minimize downstream component damage.
- Industrial Durability: Fiberglass body construction stands up to the thermal stresses of commercial HVACR applications.
Is the S1-FRNR70 a direct replacement for standard 70A fuses?
Yes, provided the system requires a Class RK5 250V fuse. Its time-delay feature makes it specifically suited for inductive loads like motors and transformers.
Can I use this fuse in a 125V DC circuit?
The Bussmann Fusetron FRN-R series is typically rated for 250V AC and up to 125V DC, but you must verify the specific manufacturer data sheet for your DC application requirements.
What happens if I replace this with a fast-acting fuse?
Using a fast-acting fuse instead of this time-delay fuse will likely result in nuisance blowing during motor startup due to the lack of "surge" tolerance.
