FAQs
The SC-5 uses ferrule end x ferrule end terminals and a compact 1.31 in length, designed for straightforward insertion into standard fuse holders and panel rails. Use ferrule crimp connections that match the ferrule ends, verify correct amperage and voltage ratings, and ensure the surrounding wiring clearance supports the 0.41 in x 0.41 in footprint.
Key specs include a 5 A amperage rating, Class G fast-acting operation, and current limiting to reduce fault energy. It provides 100 kAIC interrupt rating at 600 Vac and 10 kAIC at 170 Vdc, with voltage ratings of 600 Vac and 170 Vdc, respectively. The device is non-indicating and RoHS/CE compliant.
SC-5 supports both AC and DC circuits with 600 Vac and 170 Vdc ratings, making it suitable for control panels, MCCs, and DC-powered automation loops. Its high interrupt ratings help protect downstream devices from faults, while its current-limiting capability minimizes arc duration and equipment damage during faults.
The SC-5 is CE marked and RoHS compliant, ensuring conformity with European electrical safety and environmental standards. These certifications support regulatory approvals for commercial and industrial deployments, simplify supplier qualification, and reduce risk during audits and product lifecycle management.
Using SC-5 can lower maintenance costs by reducing nuisance trips and downstream damage due to its current-limiting, fast-acting performance and high interrupt ratings. The rejection-style design also reduces incorrect substitutions, simplifying spare-part management and improving field reliability, which translates to improved uptime and lower total cost of ownership.
