The VALUE COLLECTION BDC21722 is a Class J general-purpose fuse rated at 20 amps, designed for plug-in mount applications in electrical distribution and protection systems. Sold in a 2-pack, this blue-body fuse provides reliable overcurrent protection in branch circuit and equipment panels. Class J fuses are recognized for their current-limiting performance and are commonly specified in commercial and industrial electrical systems where space and safety ratings matter. Installation is performed by licensed electricians working on properly rated fuse holders and disconnect equipment.
This fuse is suited for use in plug-in fuse blocks and holders that accept Class J form-factor fuses. Typical applications include motor branch circuits, control panel protection, and equipment disconnect assemblies in commercial and light industrial environments. The 20-amp rating positions it for moderate-load circuits requiring reliable overcurrent response. The blue color coding aids in quick amperage identification during service and inspection.
Designed for use in plug-in fuse holders and fuse blocks that accept Class J form-factor fuses rated for 20-amp service.
Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or inserting fuses. Verify that the fuse holder or fuse block is rated for Class J fuses and for the circuit voltage and amperage before installation. Do not substitute a higher-amperage fuse to bypass a tripped overcurrent condition.
