General Electric | SB463WG | Fusible Bus Plug | 100A | 600V

General Electric's SB463WG Fusible Bus Plug is a dependable, drop-in protection component engineered for 100A circuits in 600V distribution systems. Whether you’re performing routine maintenance, upgrading existing gear (retrofit), or replacing a worn component, this GE part is designed to slot into compatible bus plug assemblies with minimal downtime and predictable performance.

Key specifications

• Amperage: 100A
• Voltage: 600V
• Product type: Fusible bus plug
• Part number: SB463WG
• Brand: General Electric (GE)
• Applications: maintenance, retrofit, and replacement in compatible switchgear/bus plug systems

Best reference for compatibility: The part number SB463WG is the most accurate reference when verifying fit with GE panel and bus plug assemblies.

Why this fusible bus plug stands out

• Designed for reliable integration within GE electrical distribution setups, delivering clear protection at the bus level without requiring extensive system alterations.
• Inline compatibility with 600V systems makes it suitable for a range of commercial or industrial applications where robust overcurrent protection is needed at the source.
• Precise 100A rating helps ensure appropriate fault current handling and protective coordination within your existing protection scheme.

Ideal use cases

This fusible bus plug is well-suited for facilities performing:

• Maintenance: quick replacement to restore protected bus paths and minimize downtime.
• Retrofit: upgrading older gear to maintain or improve protection without a full panel overhaul.
• Replacement: when a like-for-like GE part is required to match existing protection coordinates and system design.

Installation and safety notes

• Always confirm fit and ratings before ordering to ensure proper alignment with your GE equipment.
• Follow standard electrical safety practices: de-energize circuits, use appropriate PPE, and refer to the equipment’s datasheet and site procedures during installation.
• Keep spare SB463WG units on hand to reduce downtime during routine maintenance or unexpected failures.

What problems this solves

By providing a defined, part-number-specific fusible connection at the bus level, this plug helps protect downstream equipment, limit fault impact, and support faster service turns in GE-supported switchgear environments. It’s a targeted solution for technicians who need a reliable, compatible replacement part that aligns with existing protection schemes and ratings.
