SB462RG 60A, 480/600V, 3-Phase, 4-Wire Fusible Bus Plug

Meet the SB462RG from GE—a purpose-built 60A, 480/600V fusible bus plug engineered for 3-phase, 4-wire power systems. As part of the GE Spectra Series, this bus plug is designed to integrate smoothly with GE switchgear and panel configurations, delivering a compact, reliable solution for protected bus connections in demanding industrial environments.

• Current rating: 60 A
• Voltage rating: 480/600 V
• Configuration: 3-Phase, 4-Wire
• Type: Fusible Bus Plug
• Series/Manufacturer: GE Spectra Series

Why the SB462RG matters

This fusible bus plug places protective coordination right at the bus connection point, helping to isolate faults quickly and protect downstream equipment in heavy-duty distribution networks. Its 480/600V rating makes it well-suited for industrial facilities, manufacturing floors, and large commercial installations that rely on robust three-phase power with a four-wire system. By enabling an integrated fuse interface within the bus plug, it reduces wiring complexity and simplifies protection schemes in Spectra Series environments.

Ideal use scenarios

• Industrial facilities running 480/600V 3-phase, 4-wire distribution
• Factories, machine shops, and process plants needing reliable inline protection at the feeder level
• Facilities upgrading protection modules within GE Spectra Series panelboards or switchgear

What makes it unique

Unlike generic bus plugs, the SB462RG is purpose-built for GE Spectra Series systems, ensuring compatibility with existing protection strategies and panel layouts. The fusible design provides an integrated protection point at the bus interface, helping to streamline installation and fault isolation without the need for additional separate fusing components in the immediate circuit path.

Installation and practical tips

• Verify system voltage and confirm a 3-phase, 4-wire configuration before installation
• Pair with GE-compatible fuses and protection devices designed for Spectra Series panels
• Inspect the bus plug for signs of wear or overheating after commissioning and during routine maintenance
• Keep spare SB462RG components on hand to reduce downtime during maintenance or replacements
