General Electric | SB463R | Fusible Bus Plug | 100A | 3-Pole | 600V

General Electric introduces the SB463R Fusible Bus Plug—a precise, field-ready solution designed for industrial electrical systems. With a 100A rating across 3 poles and a 600V limit, this GE component is built to support maintenance, retrofit, and replacement projects where exact specifications matter. The SB463R is your dependable reference point for adding or restoring fusible protection in compatible switchgear and bus duct assemblies.

Key specifications

• Amperage: 100 A
• Poles: 3-Pole
• Voltage: 600 V
• Part number: SB463R
• Brand: General Electric (GE)

Why this fusible bus plug stands out

• Exact-match compatibility: engineered to fit specific GE equipment that accepts 3-pole, 600V fusible bus plugs, reducing guesswork during maintenance or retrofit.
• Clear identification: the SB463R part number is the most reliable reference for ensuring proper fit and ratings in your system.
• Targeted protection: integrates fusible protection directly into the bus plug, enabling controlled isolation and safeguarding downstream equipment during service or fault events.
• Industrial-grade robustness: designed to withstand the rigors of demanding environments where reliability and predictable performance are critical.

Fit, compatibility, and what to verify

Before ordering, confirm that your equipment accepts a 3-pole, 100A, 600V fusible bus plug of the SB463R specification. The part number is the best reference to ensure seamless compatibility with your GE switchgear or bus duct assembly.

Installation and safety considerations

For safe installation, ensure the following: the electrical system is fully de-energized and lockout/tagout procedures are in place; verify the 600V rating and 100A amperage align with your equipment’s requirements; and follow all applicable electrical codes and GE installation guidelines. If you’re replacing an existing bus plug, compare both the physical interface and the connector configuration to confirm a proper, secure fit.

Ideal use cases

• Maintenance: swap in a ready-to-use fusible bus plug to service aging protection components without a full system overhaul.
• Retrofit: upgrade or modify existing switchgear configurations to restore or enhance protective coordination.
• Replacement: inventory a reliable GE SB463R as a spare part to minimize downtime when a fusible bus plug is needed.
• Spare for critical facilities: keep on hand to reduce downtime during scheduled maintenance or unforeseen outages.

Practical tips for best results

• Document the exact equipment model and verify it accepts the SB463R specification to avoid mismatches during planning.
• Store spare bus plugs in a dry, clean area to maintain connector integrity and ensure quick deployment when needed.
• Coordinate with your maintenance schedule to align fusible plug replacement with routine inspections, reducing operational risk.
