• Part number: SB323RJ

What makes the SB323RJ unique

• Fusible bus plug design provides integrated overcurrent protection, simplifying wiring and reducing assembly steps in compatible GE panels.
• Three-pole configuration ensures balanced, symmetrical protection across all phases, essential for three-phase distribution systems.
• Engineered to align with GE equipment tolerances and mounting footprints, enabling straightforward retrofits without modifying the enclosure.
• Built for reliability in industrial environments with robust connector interfaces and GE’s proven manufacturing standards.

Ideal use cases

• Maintenance and retrofit projects in GE switchgear or panel boards requiring a direct 100A, 3-pole, 240V fusible plug.
• Replacement for aging bus plugs where the SB323RJ matches the original part number for compatibility.
• Field servicing of industrial equipment that relies on fast, compatible fuse protection in a compact form factor.

Compatibility and verification

Before ordering, confirm fit and ratings against your equipment. The part number SB323RJ is the most reliable reference for compatibility with GE panels and similar assemblies. Check:

• Panel or switchgear model and bus arrangement
• Rated voltage and amperage requirements
• 3-Pole configuration and mounting footprint

Installation and safety notes

Work should be performed by a licensed electrician or qualified technician. Ensure the system is de-energized and follow all applicable electrical codes and safety practices. The fusible nature of this bus plug is designed to protect circuits by interrupting fault currents, but proper sizing and correct installation are essential for effective protection.

How it compares to alternatives
