General Electric | SB361 | Fusible Bus Plug | 30A | 3-Pole | 600V

The General Electric SB361 Fusible Bus Plug is an OEM-grade protective component engineered for reliable performance in GE switchgear and bus duct systems. With a 30A rating across 3 poles at 600V, this plug delivers precise, fast-acting fault interruption, making it a dependable choice for maintenance, retrofit, or replacement projects.

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 600V
• Part Number: SB361
• OEM: General Electric

Where this fits in your electrical system

Designed for use in equipment that requires a fusible link to protect feeders and switchgear, the SB361 slots into GE bus assemblies where a dedicated, replaceable protective element is needed. It’s ideal for maintenance windows, retrofits, and replacement scenarios—helping you restore protection quickly without re-engineering the surrounding hardware.

Why the SB361 stands out

• OEM compatibility: Precisely matches GE bus bar geometry and terminal interfaces for a seamless, reliable fit.
• Defined protection: 3-pole configuration with a 600V rating provides coordinated protection across multiple conductors.
• Fast, predictable interruption: Fusible design ensures rapid fault clearing, minimizing damage to upstream equipment.
• Maintenance-friendly: Easy to replace during scheduled downtime, reducing mean time to repair (MTTR).

How it works and practical use cases

In normal operation, the SB361 remains seated within the bus plug housing, allowing uninterrupted current to pass through. When an overcurrent or fault condition occurs, the internal fusible link opens the circuit, isolating the fault and protecting downstream components. This makes it particularly suitable for:

• Upgrading aging switchgear where a compatible fusible plug is required
• Stocking spare parts for rapid replacement during routine maintenance
• Retrofit projects that demand an exact GE-compatible plug to avoid fitment issues

Important compatibility and ordering notes

Before purchasing, verify fit and ratings against your equipment. The part number SB361 is the most reliable reference for compatibility, ensuring the plug aligns with your GE bus configuration and voltage class. If your panel or switchgear specifications list this exact part and rating, you’re aligned for a straightforward replacement or retrofit.

Practical tips for storage and installation

• Keep spare SB361 fusible bus plugs in a clean, dry environment to prevent corrosion and ensure immediate readiness.
• Label replacements clearly and store them with compatible GE components to streamline future maintenance.
• During installation, follow standard PPE and de-energization procedures; confirm all connections are torqued to manufacturer specifications to maintain reliable contact.
