Product description
SV Fuse holder, Class J, 201-400 A, 600 V, 3-pole, (60 mm)
The SV 9345.400 fuse holder provides a 3-pole Class J solution rated 201-400 A at 600 V, delivering a broad protection window that supports safe isolation of heavy loads while meeting UL 248-8 performance requirements. This feature translates to reduced risk of under- or over-fusing and more predictable system behavior in industrial cabinets. The 60 mm centre-to-centre spacing standardizes panel assembly, cutting installation time and minimizing misalignment risk, while remaining compatible with existing RiLine busbar grids. Box-terminal connections for round conductors (AWG 4/0 – MCM 600) with top/bottom cable outlets offer routing flexibility, simplifying wiring in tight spaces and reducing installation errors. Compliance with UL 508 and UL 248-8, plus UL-listed accessory status when used with RiLine systems, lower audit risk and accelerate commissioning. Material choices — polyamide housing with silver-plated copper contacts — provide flame retardancy, low contact resistance, and robustness against vibration, supporting long-term reliability in harsh industrial environments. Overall, these features enable improved maintenance intervals, reduced total cost of ownership, and safer, more efficient power distribution in control panels.

FAQs
The SV 9345.400 is designed as a 3-pole Class J fuse holder for 60 mm busbar spacing and is compatible with RiLine busbar assemblies. It uses a box-terminal connection for round conductors (AWG 4/0 – MCM 600) and top/bottom cable outlets, enabling straightforward integration in RiLine-based panels and other standard enclosures.
This fuse holder supports Class J fuses with a rated operating current up to 400 A and a minimum of 201 A, rated for 600 V, 3-phase. It complies with UL 248-8 fuse standards and UL 508 electrical standards, providing reliable protection and clear regulatory alignment for industrial power distribution.
Yes. With 3 poles, 60 mm busbar spacing, and a 600 V rating, the SV 9345.400 is well-suited for 3-phase protection in industrial cabinets and control panels. Its Class J fuse compatibility and robust copper contacts support stable current interruption and safe operation in demanding environments.
The unit carries UL 508 standards and UL 248-8 fuse standards, with a note that it is a UL-listed accessory when used on RiLine busbar systems. These certifications provide regulatory confidence for safety and performance in industrial electrical installations.
The fuse holder enables quick fuse replacements due to straightforward top/bottom cable routing and box-terminal connections, reducing downtime. Its durable polyamide housing and copper contacts minimize wear, supporting longer service life and lower maintenance costs over the equipment’s lifecycle, contributing to a favorable total cost of ownership in power distribution applications.
