The 45 A Class G current-limiting SC fuse delivers fast-acting protection that minimizes arc exposure and downstream damage, boosting overall equipment reliability and reducing repair costs in control panels and machine enclosures. In practice, this translates to fewer interruption events and shorter downtime during overloads, supporting predictable maintenance schedules and safer start-up sequences in automated lines. The 100 kAIC interrupt rating at 480 Vac and 10 kAIC at 300 Vdc provides robust fault-current clearance for high-energy circuits, enabling safe operation of motors, drives, and power supplies while meeting industry safety expectations. Rejection style construction prevents incorrect substitutions, improving inventory control and field reliability in complex panel assemblies. Ferrule end x ferrule end connections simplify termination with standard crimp practices, delivering faster, cleaner installations and reduced field wiring errors. The fuse’s compact dimensions (0.41 in W/D, 2.25 in H) and 0.35 lb weight support easy mounting in crowded enclosures, preserving panel real estate. Non-indicating status helps keep control indicators uncluttered in diagnostic-rich environments, while CE Marked and RoHS compliant features support global compliance programs and sustainability goals.

FAQs
SC-45 uses ferrule end x ferrule end terminals, designed for quick, secure crimp connections in standard control panels. Its compact 0.41 in width and 2.25 in height fit tight enclosures, while the 0.35 lb weight minimizes panel load. Installing this fuse with compatible ferrule terminals reduces wiring errors and speeds up commissioning in industrial environments.
SC-45 provides a 100 kAIC interrupt rating at 480 Vac and 10 kAIC at 300 Vdc, enabling safe interruption of high-energy faults. Its fast-acting, current-limiting design helps constrain fault current to protect downstream components, reducing damage to transformers, drives, and control electronics and shortening downtime after a fault condition.
Yes. The SC-45 is rated for 480 Vac and 300 Vdc circuits, with a 45 A amperage rating. This makes it appropriate for industrial control panels and machines that operate across both AC and DC supply rails, providing consistent protection across mixed systems while maintaining a compact form factor.
SC-45 is CE marked and RoHS compliant, ensuring compliance with European safety and environmental requirements. This helps streamline regulatory approvals for panels shipped to Europe and supports sustainability goals by restricting hazardous substances, aligning with broader corporate compliance initiatives.
SC-45 reduces downtime by rapidly interrupting overloads and limiting fault currents, protecting downstream equipment and extending component life. Its rejection-style design minimizes mis-parts in stocking, while ferrule terminations speed installation. Together with a compact footprint and global availability, it lowers maintenance costs and supports faster root-cause analysis in automated facilities.
