Why this fusible bus plug stands out

• : engineered to fit specific GE bus assemblies, enabling quick swaps without altering surrounding gear. The SL425WGI reference is the most reliable indicator for compatibility.
• : designed to minimize panel downtime during fuse changes or retrofit projects, so facilities stay online when you need them most.
• : built to maintain solid conductor contact and reliable fault isolation in 240V, 400A applications, reducing arcing risk and ensuring consistent protection performance.
• : suitable for upgrades, replacements, and refurbishments in industrial, commercial, and utility-adjacent environments where four-pole configurations and high-current protection are required.

Ideal use cases

• Retrofit existing electrical distribution systems to accommodate updated protection schemes without a full panel replacement.
• Replace worn or failed fusible bus plugs in 400A, 240V installations to restore reliable protection quickly.
• Stock a ready-to-install spare for service fleets that manage GE-based switchgear and bus assemblies.
• Support routine maintenance outages with parts that ensure predictable, repeatable performance when reinstalled.

Important fit and installation notes

• Always confirm fit and ratings before ordering. The part number SL425WGI is the best reference for compatibility with your GE bus assembly.
• Plan for proper de-energization procedures and qualified installation practices to maintain system safety and integrity.

Practical considerations and tips for maximizing performance

• Store and handle the bus plug in clean, dry conditions to preserve conductive surfaces and connector integrity.
• Pair this bus plug with compatible protective devices and bus hardware to ensure coordinated protection across the distribution path.
• Document the replacement part in your asset management system to streamline future maintenance and retrofits.
