Description

Fast-Acting Fuse 1A 250 Vac .25 Inch x .25 Inch x .75 Inch

Features

  • Specifically engineered to the universal 5mm diameter and 20mm length standard, this miniature fuse provides a precision fit for high-density printed circuit boards (PCBs) and modular fuse blocks. Its compact footprint makes it the ideal replacement part for global electronics, instrumentation, and power supply units where space is at a premium.
  • Designed with a highly responsive internal element, the GMA-1-R is a fast-acting (F) fuse that clears short circuits and overloads almost instantaneously. By sacrificing itself before delicate semiconductors or digital circuits are exposed to excess current, it prevents permanent hardware damage and saves you the high cost of replacing entire electronic modules.
  • Calibrated for precise 1-amp current delivery at voltages up to 250V AC, this fuse provides a targeted safety barrier for low-amperage devices. The clear glass tube allows for immediate visual verification of a blown filament, enabling technicians to identify faults at a glance without needing to pull out a multimeter for every diagnostic check.
  • This Bussmann Series fuse is fully RoHS compliant (lead-free) and UL 248-14 listed, ensuring it meets the strictest global environmental regulations and North American safety benchmarks. Utilizing a certified, high-quality component ensures your repairs are safe, reliable, and compliant with both manufacturer warranties and local electrical inspections.
