Standard Blade Fuse Holder

The Standard Blade Fuse Holder FB4 is a compact 4 way blade fuse block designed for use in automotive, marine and general low voltage electrical systems. It accepts standard 19 mm blade fuses and provides a tidy, reliable method of distributing multiple fused circuits from a single point. The holder is built with a strong, impact resistant body that keeps fuses secure and helps protect connected wiring.

With dimensions of 52 mm length, 58 mm height and 26 mm width, the holder is sized for installations where space is limited, such as dashboards, engine bays, control panels or compact distribution boards. Each of the four circuits connects via 6.3 mm male blade terminals, offering a widely used and dependable connection method.

The design supports straightforward mounting on flat surfaces, and the moulded mounting features make alignment and fixing simple for professional installers. The FB4 is suitable for typical 12 to 32 V DC systems, making it ideal for a wide range of applications including vehicles, boats, off grid systems and auxiliary power control setups.

Its four circuit positions allow installers to distribute power to multiple accessories or subsystems while maintaining clear protection and isolation. This can include lighting, pumps, electronics, charging accessories or auxiliary equipment. The compact format keeps the overall installation tidy and avoids unnecessary clutter within wiring looms.

By incorporating a purpose built fuse holder rather than inline fuses, technicians gain a cleaner system layout, easier diagnostics and faster fuse replacement when required. The FB4 aligns with best practice for organised, serviceable and safe power distribution in both new installations and retrofits.
