• Amperage: 30 A
• Poles: 3‑Pole
• Voltage: 480 V
• Part reference: SB311ED4G

Why this matters: the SB311ED4G is engineered to align precisely with GE equipment specifications, providing a dependable, plug‑and‑play solution when upgrading or refurbishing three‑phase distribution paths. The exact part number is the best reference for compatibility, helping you avoid mismatches and costly downtime.

Key advantages that set this bus plug apart:

• Direct compatibility for GE switchgear — designed around GE’s standard bus plug footprint and electrical interface to streamline replacements and retrofits.
• Minimized downtime — a straightforward installation path that supports rapid service interruptions with predictable performance.
• Consistent 480V three‑phase operation — reliable performance in industrial environments requiring stable, balanced distribution across three conductors.
• Future‑proof retrofit option — ideal for upgrading aging gear or expanding capacity in facilities that already use GE components.

This bus plug is ideal for engineers, maintenance crews, and facilities managers working in manufacturing plants, data centers, and other industrial settings where 480V three‑phase power is standard. It addresses common challenges such as equipment downtime, misfit replacements, and the need for dependable, documented part references in repair and upgrade projects.

Important note: Confirm fit and ratings before ordering. The part number SB311ED4G provides the clearest compatibility reference for your GE equipment, ensuring a precise match for your application.

Use scenarios and practical applications:

• Maintenance outages where a non‑disruptive, compliant bus plug replacement is required to restore or sustain service.
• Retrofits to upgrade older gear to current GE standards without a full cabinet redesign.
• Replacement in systems that operate at 480V and rely on a 3‑pole configuration for balanced, three‑phase power.
• Spare part strategy for facilities with 30A, 3‑pole, 480V bus plugs to reduce procurement lead times.

Tips for optimal results:

• Cross‑check the exact GE equipment model and serial compatibility using the SB311ED4G reference before purchase.
• Plan for safe de‑energization and follow your site’s lockout/tagout procedures during replacement.
• Document the installation with part numbers and dates for future maintenance records and audits.
