Description

Fast-Acting Fuse 4A 125 Vac, 0.25 Inch x 0.75 Inch Size, Glass Tubing

Features

  • Designed with the globally recognized 5mm diameter by 20mm length footprint, this GMA-series fuse is a direct-replacement standard for a wide variety of power supplies, small appliances, and industrial instrumentation. The precise ferrule construction ensures a tight, low-resistance fit in any compatible fuse clip or panel-mount holder, preventing intermittent power issues caused by poor connectivity.
  • Engineered for rapid response, the GMA-4-R is a fast-acting (F-rated) fuse that opens almost instantly when an overcurrent condition is detected. This speed is critical for protecting delicate internal electronics and semiconductor components that cannot withstand even brief surges, significantly reducing the likelihood of permanent circuit board damage during a fault.
  • Rated to safely manage a continuous 4-amp current at up to 250V AC, this fuse provides a high level of precision for mid-range electronic circuits. The clear glass tube allows for immediate visual verification of a blown filament, enabling maintenance techs and DIYers to diagnose power failures at a glance without needing specialized testing equipment.
  • This Bussmann fuse is fully RoHS compliant and UL 248-14 listed, ensuring it is free from hazardous materials and manufactured to the highest industry safety specifications. By utilizing a certified, lead-free component, you ensure your equipment repairs remain code-compliant and environmentally responsible while maintaining a high 10kA interrupting rating at 125V AC to prevent catastrophic arcing.
