What makes the SL425RI unique

• GE-engineered reliability: Designed to meet the exacting standards of General Electric switchgear and bus architectures, delivering consistent electrical performance and protection.
• Precise compatibility: The SL425RI is the best reference for fit and ratings—essential for avoiding mismatches in older or specialized GE systems.
• Efficient maintenance pathway: As a ready-made fusible bus plug, it streamlines downtime during routine service, retrofit projects, or urgent replacements.
• Clear specifications: A clearly defined 400A rating at 240V helps you plan upgrades or replacements with confidence, reducing guesswork on interchangeability.

Ideal use cases and practical scenarios

Whether you’re updating aging infrastructure or performing a targeted retrofit, the SL425RI serves as a reliable bridge between existing bus bars and protective fusing. Use cases include:

• Maintenance windows: Swap in the SL425RI to restore protected bus paths quickly during scheduled downtime.
• Retrofits: Integrate a fusible link into a 240V, 400A distribution path where GE panels require a plug-style protection point.
• Parts replacement: Keep the part number SL425RI on hand as a direct substitute for compatible configurations to minimize project delays.
• System protection alignment: Ensure that protective devices match the panel’s design specs, helping to maintain coordinated protection across feeders.

Compatibility and installation considerations

Before ordering, verify fit and ratings against your specific panel configuration. The SL425RI is identified by GE part number SL425RI, making it the most reliable reference for compatibility in corresponding switchgear assemblies. When selecting this fusible bus plug, consider:

• That the panel’s bus design and connector geometry align with the SL425RI’s specifications
• That the operating voltage and current ratings match your application requirements (240V, 400A)
• That proper de-energization and lockout/tagout procedures are followed during installation

Care, handling, and storage

To preserve performance and safety, store the SL425RI in a clean, dry environment and handle with standard electrical PPE. When installing, ensure connections are clean, torqued to the manufacturer’s recommendations, and free of contamination to maintain a reliable fuse path and electrical integrity over time.

Designed for professionals maintaining or upgrading General Electric distribution systems, the SL425RI Fusible Bus Plug delivers a precise, dependable solution for 240V, 400A applications. Use it as a targeted, drop-in protection component in suitable GE panel configurations, and rely on its clear part-number guidance to keep your maintenance and retrofit projects on track.
