Application
Designed as a direct OEM replacement for York HVAC systems, the S1-FRNR25 is ideal for use in furnaces, air handlers, rooftop units, and other commercial and residential HVAC equipment requiring 250V, 25A time-delay fuse protection. Always verify your equipment’s fuse specifications before installation.
Why Choose a Time-Delay Fuse?
Time-delay fuses are specifically engineered for motor-driven applications. The dual-element construction absorbs the high inrush current that occurs when a motor starts, preventing unnecessary fuse blowing while still providing fast, reliable protection against short circuits and sustained overloads.
