With a clear 100A rating at 600V, it plugs into compatible bus assemblies to provide fast-acting protection while maintaining system continuity in normal operation.

Designed for critical maintenance, retrofit, and replacement

Whether you're upgrading an aging panel, replacing a worn component, or performing a retrofit, this fusible bus plug ensures you match the exact specifications your equipment demands. The SB463WGI is specifically identified by its part number, making cross-reference straightforward and reducing guesswork during service projects.

Key specifications

• Amperage: 100A
• Voltage: 600V
• Part number: SB463WGI

Why this matters

In power distribution, precise ratings and reliable fusible protection are essential. This bus plug integrates with GE-switchgear and bus duct configurations to provide a controlled, safe interruption when a fault occurs, helping to protect transformers, breakers, and downstream equipment. The fusible design limits fault energy and isolates the affected circuit quickly, supporting safer maintenance windows and longer equipment life.

Use cases and ideal applications

• Maintenance: replace worn fusible components in GE-compatible panels without redesigning the system.
• Retrofit: upgrade older installations to current GE-compatible bus protection with the SB463WGI.
• Replacement: source a like-for-like substitute when stocking service parts for GE equipment.

Fit, compatibility, and installation notes

Before ordering, verify that the SB463WGI aligns with your equipment's fit and ratings. The part number is the best reference for compatibility, ensuring you select the correct interface, mounting, and electrical characteristics for your specific GE gear.

Reliability and safety you can trust

General Electric's engineering standards underpin this fusible bus plug, designed to withstand industrial environments and deliver predictable performance when it matters most. By matching the exact amperage and voltage, you help protect personnel, maintain uptime, and reduce the risk of damage from electrical faults.
