Description
This 30 Amp MDA Style Ceramic Slo Blo Fuse is designed for hot tub and pool equipment control boards. Measuring 1 1/4" in length by 1/4" in width, this automotive-grade protective component features ceramic construction for superior heat dissipation rather than traditional glass. Due to the opaque ceramic material, visual inspection cannot determine fuse condition—testing with a multimeter across terminals is required to verify continuity. Important: Given the larger amperage rating for circuit board applications, this fuse may fail gradually from thermal stress. If your fuse has blown, simply replacing it may provide only temporary relief—underlying electrical issues should be investigated to prevent recurring failures.
