FAQs
The FRS-R-7-1/2ID is ideal for motor control circuits, drives, and feeder protection in industrial panels. Its time-delay, dual-element design handles inrush with minimal nuisance trips, while the 7.5 A rating and high interrupt capacity safeguard equipment from short circuits. Use it in control panels, MCCs, and distribution boards where predictability and rapid fault clearing are critical.
The fuse provides a 7.5 A amperage rating, 600 Vac voltage rating, and 300 Vdc capability. It offers a 200 kAIC interrupt rating at 600 Vac and a response time of about 10 seconds at 500% overcurrent, making it suitable for balanced protection against both short circuits and overloads in mixed AC/DC environments.
Yes. This device is part of the Bussmann RK5 class family, designed for compatibility with standard RK5 fuse holders and Bussmann catalogs. Its compact 5 inch length and 0.81 inch width/height simplify replacement and upgrades in existing RK5 panel installations, enabling straightforward retrofit projects and consistent protection across panels.
The FRS-R-7-1/2ID is CE Marked, reflecting compliance with European safety and performance standards for electrical protection devices. While it adheres to RK5 class family specifications and industry best practices, users should verify any additional site-specific regulatory requirements and cross-check with local electrical codes during panel design and commissioning.
