General Electric | SL325RGI | Fusible Bus Plug | 400A | 3-Pole | 240V

Meet the General Electric SL325RGI Fusible Bus Plug—a purpose-built 400A, 3-pole, 240V protection module designed for GE switchgear systems. This fusible bus plug delivers clean, reliable protection at the point of connection, making maintenance, retrofit, and replacement workflows faster and more predictable while preserving your protection scheme’s integrity.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 240V
• Type: Fusible bus plug
• Brand/Part: General Electric, SL325RGI

Why this fusible bus plug stands out

Unlike generic replacements, the SL325RGI is engineered to align with GE’s switchgear architecture, ensuring precise fit and electrical coordination. Its three-pole configuration supports synchronized protection across all three phases, which is critical for maintaining voltage balance and minimizing fault impact. The fusible design allows for straightforward field replacement—you swap in the plug, restore service, and keep your protective relay and upstream devices protected without complex alterations.

Ideal use cases

• Maintenance outages where a quick, reliable protection insert is needed to restore service.
• Retrofit projects upgrading older gear to current protection schemes without a full panel replacement.
• Replacement of worn or obsolete bus plugs to maintain system integrity and protection ratings.
• New installations requiring a precise 400A, 3-pole, 240V fusible interface within GE switchgear.

Fit, compatibility and installation tips

To ensure seamless operation, verify that your equipment's ratings and pole count match the SL325RGI’s 400A, 3-pole, 240V specifications. Use the part number as the clearest compatibility reference during procurement, and double-check the bus plug’s connection geometry matches your GE switchgear model. For technicians, plan a straightforward, controlled replacement procedure—power down, isolate, replace the plug, and test protection coordination to confirm the fuse link and circuit integrity behave as designed.

Practical benefits and outcomes

• Minimized downtime with a field-ready, replaceable protection point
• Maintains coordinated protection across all three phases at 240V
• Specifically matched to GE equipment, reducing guesswork during upgrades
• Clear part reference (SL325RGI) simplifies ordering and compatibility checks

Note: Confirm fit and ratings before ordering. The part number is the most reliable reference for compatibility, ensuring you select the exact General Electric fusible bus plug required for your configuration.
