Determine & Increase Panel SCCRs with Littelfuse | THE PROBLEM: Many Customers Have Problems Determining a Panel's SCCR. Many OEMs struggle when calculating a panel's SCCR, and MROs are often unsure if the SCCR of a panel is sufficient for their circuit protection needs. If the available fault current of the electrical system where the panel is installed exceeds the SCCR of the panel—and a short circuit occurs—catastrophic damage to the panel may occur, and electrical workers and others are put at risk of injury.
THE SOLUTION: Littelfuse Provides Products and Training That Can Increase a Panel's SCCR. Littelfuse offers fuses and power distribution blocks with higher SCCRs that can increase the overall SCCR of your customers' industrial control panels. And our technical information provides examples and methods that simplify the process of determining if a panel will be acceptable to consulting engineers and inspectors.

Current-limiting Fuses Provide 200 kA Protection | Current-limiting fuses have interrupting ratings of 200,000A that can significantly increase any 'weak link' component ratings when evaluating all the individual and combination-rated components within a panel. The panel's overall SCCR can be dramatically increased while also providing optimal circuit protection performance.

|
Littelfuse Power Distribution Blocks...with UL Approved Higher Ratings | Littelfuse power distribution blocks are now UL Approved with higher 50 kA, 100 kA, and 200 kA SCCRs instead of the 10 kA default rating. These products should be used in industrial control panels to replace other devices with lower interrupting ratings or capacities, thus increasing the panel's overall SCCR.
