Electrical components are necessary elements for industry and households. Specialty fuses are electrical protection devices that provide a means of limiting the amount of electrical current that flows through a circuit. The 68300 fuse is a dual element time-delay fuse designed for heavy-duty commercial and industrial applications. This fuse has a current-limiting rule curve with a 200 kA interrupt capacity.

The 68300 provides higher levels of current limiting, requiring fewer fuses and making the system cost-effective while providing excellent protection against short circuits. The dual element time-delay characteristics make the 68300 ideal for protecting upstream low- and medium-voltage power distribution systems, which can be overloaded during a fault due to the current that is drawn by stepping motors and SCRs (silicon controlled rectifiers).

The 68300 fuse is designed for added protection to these power systems, which are often extremely expensive. In addition, the 68300 is designed for use with 3-phase systems and has an operating temperature range of -40 to 85 degrees Celsius. The 68300 fuse is UL Listed and C-UL Certified, so it is suitable for use in the US and Canada.

The 68300 also helps reduce maintenance costs and downtime due to its advanced design, allowing electrician to reset it and restore the circuit. This is made possible by the Amtech LED communication technology, which allows the fuse to self-diagnose various problems, guaranteeing both maintenance and safety.

The 68300 fuse also offers other features, like continuous current rating of 100 Amps and voltage rating of 600V, designed for use in a wide range of Industrial and Commercial applications. The 68300 fuse’s operating voltage range is also from 690V up to 6,300V. Furthermore, its Compact size ensures easy installation and it is engineered to provide high levels of performance and reliability.

The 68300 fuse has other protection features, such as its dual element design, which is comprised of a current-limiting main element and a current-limiting series-fuse protection element. The series-fuse element provides an additional layer of protection against damaging faults. The 68300 also has a voltage independent trip characteristics of 400V AC, allowing it to protect a wide variety of applications.

The 68300 combines current limiting protection and dual element time-delay characteristics for use in industrial and commercial applications with high fault currents. It has a one-step time-delay principle that assures protection against damaging short circuit currents and overloads. Its features make it the perfect choice for providing efficient electrical protection in direct and indirect environments.
