Gecko PCB fuse 500mA

500mA, 250v glass fuse 20mm long x 5mm diameter. All fuses are tested prior to dispatch Fuses carry no warranty due to their consumable nature - these fuses have been tested for continuity and are operable. Do not replace a blown fuse without first determining the reason for failure as the replacement of the fuse may result in subsequent fuse failure a second time. Fuses fail through long term stress, low voltage/high current fluctuations, and from equipment failure. Repeated fuse failure may require testing of incoming power supply voltages if spa equipment has tested OK.
