Ideal for

• Maintenance teams performing routine servicing on GE panels that require a verified 60A, 4-pole, 240V fusible plug
• Retrofits that update protection schemes or replace worn, damaged, or discontinued bus plugs
• Replacement scenarios where exact GE specifications are essential to maintain warranty and system integrity

Installation and compatibility tips

• Verify before ordering: The part number SB422HFKI is the most reliable compatibility reference. Confirm the fit and ratings against your GE panel model and service manual.
• Safety first: Power down the equipment and follow all local electrical codes and lockout/tagout procedures before servicing panels.
• Proper matching matters: Ensure the 60A rating and 4-pole configuration align with the protected circuits and feeder requirements in your panel.
• Inspect and replace in sequence: If you’re upgrading protection on a multi-pole circuit, plan replacements to maintain coordinated protection across all poles.
• Storage and handling: Keep the bus plug clean, dry, and free from physical damage to preserve insulation integrity and ease of installation.

For professionals seeking a reliable, GE-endorsed solution that aligns with established panel architectures, the SB422HFKI Fusible Bus Plug delivers predictable performance, straightforward compatibility, and the protection you need to keep electrical systems running smoothly. Always consult the panel’s service documentation to ensure exact fit and ratings, and rely on the part number SB422HFKI as the definitive compatibility reference.
