The SC-7 fuse offers a 7 A amperage rating and a 600 Vac / 170 Vdc voltage rating, delivering fast-acting, current-limiting protection that minimizes fault damage and downtime in control panels and machine tools. This translates to longer equipment life, reduced maintenance costs, and safer startup sequences for automated lines. Its 100 kAIC interrupt rating at 600 Vac and 10 kAIC at 170 Vdc ensures robust fault handling even in high-short-circuit environments, improving system reliability and reducing the risk of cascading failures in harsh industrial settings. The rejection-style design prevents incorrect fuse installation in panels, improving safety and helping maintain proper coordination with upstream protection. With its standard packaging and compact form factor (1.31 in length, 0.41 in width, 0.41 in height), the SC-7 fits dense enclosures and supports straightforward field replacement. Non-indicating fuse indicators simplify panel aesthetics while allowing integration with existing monitoring schemes. RoHS and CE compliance streamline regulatory acceptance, supporting global deployments in line with electrical safety requirements and environmental regulations. The 12-second response time at 200% overcurrent provides predictable protection without sacrificing normal operation, making it a practical choice for varied loads in automation systems.

FAQs
SC-7 is designed to drop into standard Class G Bussmann series fuse installations with the same form factor and mounting footprint as other Class G fuses. The device measures 1.31 inches long, 0.41 inches high and 0.41 inches wide, and uses a rejection-style mechanism to prevent incorrect insertion in panels that expect a precise fuse type. This streamlines replacement and minimizes downtime during upgrades or maintenance.
SC-7 is a 7 A fast-acting, current-limiting fuse rated for 600 Vac and 170 Vdc. It provides a 100 kAIC interrupt rating at 600 Vac and 10 kAIC at 170 Vdc, with a response time of 12 seconds at 200% overcurrent. These specs enable robust protection for high-energy loads while maintaining safe startup and fault clearance in automation circuits.
SC-7 offers a high interrupt capacity suitable for many industrial fault scenarios, with 100 kAIC at 600 Vac. For motor inrush, engineers should perform time-current coordination to ensure the fuse clears faults without nuisance tripping during startup. In practice, SC-7 protects downstream equipment by limiting fault current while allowing normal motor inrush under controlled conditions.
SC-7 carries RoHS compliance and CE marking. These certifications support regulatory conformity for European and RoHS-restricted environments, simplifying procurement decisions in regulated facilities and ensuring alignment with environmental and safety requirements in industrial installations.
Using SC-7 can reduce maintenance costs by lowering nuisance trips and shortening downtime during fault events, thanks to its high interrupt rating and precise current limiting. The robust protection helps extend equipment life, minimize unplanned outages, and improve line availability, delivering measurable returns through increased uptime and safer, more predictable automation performance.
