General Electric | SB422SFPGI | Fusible Bus Plug | 225A | 4-Pole | 600V

General Electric presents the SB422SFPGI Fusible Bus Plug — a precise, reliable solution for mid-range distribution needs. With a 225A ampacity, 4-pole configuration, and a 600V rating, this bus plug is engineered to integrate seamlessly into GE equipment for maintenance, retrofit, or replacement projects where exact specifications matter.

Why this fusible bus plug stands out

• Exact GE compatibility: The part number SB422SFPGI is the best reference for ensuring a perfect fit with compatible GE switchgear and bus assemblies.
• Clear electrical capacity: 225A ampacity supports essential feeders while preserving protection margins in the system.
• Four-pole design: Accommodates multiple feeders or circuits within a single plug, simplifying wiring and reducing panel clutter.
• 600V insulation rating: Suitable for medium-voltage distribution environments, delivering safe operation within standard GE installations.
• Fusible protection: Enables quick isolation during overcurrent events, helping to maintain system uptime and safety during maintenance or retrofit work.

Ideal use cases

• Maintenance: Replacing aging or degraded fusible bus plugs to restore reliable protection in GE panels.
• Retrofit: Upgrading existing switchgear to match current protection schemes without extensive rework.
• Replacement: Stocking a compatible, ready-to-install part for emergency repairs in critical infrastructure.
• New installations (where specified): When your design requires a 225A, 4-pole, 600V fusible bus plug with GE heritage.

Fit and compatibility guidance

Before ordering, confirm the match against your equipment’s specs. Use the SB422SFPGI part number as the definitive reference to ensure compatibility with GE bus assemblies and compatible panels. Verify the panel's voltage class (600V), the required ampacity (225A), and the number of poles (4) to avoid mismatches during maintenance or retrofit projects.

Practical tips for installation and use

Handle with the circuit de-energized and follow proper lockout/tagout procedures. Have the correct fuse elements and compatible GE tooling ready to minimize downtime. Store spare SB422SFPGI bus plugs in protective packaging and label for rapid deployment during routine maintenance or emergency replacements. If you’re replacing an existing plug, compare the orientation and connector interfaces to ensure a smooth, fault-free installation.
