Fuseology is the study of the fuse’s fundamental operating principles. These include the ratings and operating characteristics that make the fuse an efficient overcurrent protective device (OCPD) as well as its construction that creates its unique leadership role in circuit protection. In the simplest terms, a fuse is an overcurrent protective device with a circuit-opening fusible part that is heated and severed by the passage of overcurrent through it. A fuse is comprised of all the parts that form a unit that can perform these functions. It may or may not be the complete device necessary to connect it into an electrical circuit. Electrical distribution systems can be simple or complicated. Regardless, they cannot be absolutely fail-safe and are subject to destructive overcurrent events such as overloads, ground faults or short-circuits. Harsh environments, general deterioration, damage (whether accidental or from natural causes), excessive electrical system expansion or overloading are common factors leading to overcurrent events. Reliable OCPDs like the fuse shown in Figure 1 prevent or minimize costly damage to transformers, conductors, motors and many other components and loads that make up a complete power distribution system. Reliable circuit protection is also essential to electrical safety for personnel as well as avoiding severe monetary losses from power blackouts or prolonged facility downtime.

Eaton’s Bussmann™ series CH DIN-Rail fuse holders are for UL Class CC and supplemental fuses, and IEC 10x38 fuses. They are available with and without indication in 1-, 2- and 3-pole IP20 finger-safe versions. A variety of accessories extends their application flexibility and they may be ganged together to meet specific application requirements.

Today’s world is full of electronic products and electrical devices that

are susceptible to damage from overvoltage surges.

Surges caused by static discharge, capacitive and inductive loads or

lightning can quickly destroy sophisticated electronic equipment and

components used in industrial and commercial applications. These

surges cripple operations – particularly the data and communication

systems that virtually every enterprise relies upon today, including

UL® 508A panels with their reliance on control circuits.

Also, the NEC requires a listed SPD to be installed on various

equipment types including elevators on emergency systems [NEC

620.51(E)], critical operations data systems (NEC 645.18), industrial

machinery with safety interlock circuits (NEC 670.6), wind electric

systems [NEC 694.7(D)], fire pump controllers (NEC 695.15),

emergency panelboards and switchboards (NEC 700.8) and critical

operations power systems (NEC 708.20).

We offer a wide selection of Bussmann™ series surge protection

products that help assure power quality by eliminating damaging

surges.

The revolutionary BussmannTM series Low-PeakTM CUBEFuseTM delivers the smallest footprint compared to any Class CC, J or RK fuse solution — requiring up to 70% less space when combined with its unique fuse holder or UL® 98 Listed Compact Circuit Protector switch.
