20mm Glass Fuse Antisurge

Antisurge glass fuses are electrical safety devices that protect components or internal circuits from overcurrents. Antisurge fuses are used in appliances like boilers and lighting dimmer switches. They are denoted by the letter 'T,' as opposed to 'F' (which indicates a quick-blow fuse). Slow-blow or antisurge fuses can withstand a high current overflow for a short period of time without blowing.
