Eaton BK3/GBHV12.5A6F High Speed Fuse - 150 Vac/dc - GBH-V
Part Number: BK3/GBHV12.5A6F
Quick Summary
Eaton BK3/GBHV12.5A6F high speed fuse protects electrical circuits in industrial controls and panel applications. Engineers often struggle to balance fast overcurrent protection with minimal nuisance tripping in compact enclosures. This device, part of the Bussmann GBH-V family, supports a 150 Vac/dc rating and non indicating operation, enabling clean installations where status is monitored by separate indicators. With standard packaging and a documented catalog number, it aligns with common procurement and maintenance workflows. By choosing a fuse with precise time-current characteristics, engineers can improve uptime, reduce equipment wear, and simplify regulatory alignment across CE-focused facilities or SIL-driven safety programs.

FAQs
To install BK3/GBHV12.5A6F, verify the holder is compatible with the BK3 family and that the circuit voltage is within the 150 Vac/dc rating. Disconnect power, insert the fuse fully into the holder, and secure any retention features per the BK3 installation instructions. Confirm wiring polarity and torque specs per panel design, then perform a functional test before commissioning.
The GBH-V high-speed fuse provides rapid interruption to overcurrent events, minimizing fault energy and protecting downstream equipment. It is rated for 150 Vac/dc and offered as a non-indicating device, which suits control panels that rely on separate status indicators. This configuration helps reduce nuisance trips while maintaining robust protection in automation circuits.
Yes. Designed for industrial control panels, BK3/GBHV12.5A6F supports AC and DC protection with a 150 Vac/dc rating and rapid response characteristics. It fits standard BK3-based assemblies and pairs with Bussmann GBH-V protection strategies to optimize uptime in drives, circuits, and feeder applications in manufacturing environments.
Compliances for this specific part are indicated as factory-confirmed. Users should contact Eaton to verify CE, IP, or SIL-related requirements for their installation. Compliance often depends on the final enclosure, wiring, and system integration—so confirm with the manufacturer before deployment to ensure regulatory alignment.
Using a GBH-V high-speed fuse can lower downtime by rapidly isolating faults, reducing arc energy, and protecting valuable equipment. The standard packaging and clear catalog references streamline procurement, stocking, and replacements, yielding lower maintenance costs and faster part availability for panel upgrades or retrofits.
