Inline fuse holder for low-voltage HVAC control circuits. It splices into the 24 V control wiring and holds a replaceable cartridge fuse, so a short in the thermostat or control circuit blows the fuse instead of damaging the transformer or control board. Fuse rating is not published for this part – fit the amperage the equipment manufacturer specifies for the control circuit. Specifications from our own stock records. The manufacturer does not publish a public page for this item.
