General Electric | DE365RT | Fusible Bus Plug | 400A | 3-Pole | 600V

Introducing the General Electric DE365RT Fusible Bus Plug — a purpose-built 400A, 3-Pole device engineered for 600V power distribution. Designed for maintenance, retrofit, and replacement tasks, this fusible bus plug slips into compatible GE switchgear to restore protected circuits quickly and with confidence. Built on GE’s proven reliability, the DE365RT helps minimize downtime and keep critical loads protected during upgrades or service.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 600V
• Part number: DE365RT
• Applications: Maintenance, Retrofit, Replacement
• Compatibility note: Confirm fit and ratings before ordering. Part number is the best reference for compatibility.

Why this matters for your operation

In industrial and commercial electrical systems, downtime is costly. The DE365RT Fusible Bus Plug provides a reliable, drop-in solution that aligns with 600V, three-phase infrastructure. Its fusible design offers prompt fault isolation, helping protect downstream equipment while simplifying the replacement process when a component reaches end-of-life or requires an upgrade. The three-pole configuration ensures balanced protection across all phases, reducing the risk of uneven loading during repairs or retrofits.

Ideal applications

• Maintenance projects on GE switchgear where a proven, compatible fusible bus plug is required
• Retrofit installations updating legacy distributions to current GE-compatible components
• Replacement scenarios that demand exact electrical ratings and a straightforward part-number reference
• Industrial facilities and service fleets needing ready-to-install spare parts to minimize downtime

What sets it apart

The DE365RT isn’t a generic substitute — it’s a GE-certified fusible bus plug with a precise 400A, 3-pole, 600V specification. Relying on the DE365RT part number as the compatibility reference helps ensure the new plug mates correctly with your GE panels and reduces install risk. This targeted fit is especially valuable in controlled maintenance environments where exact component matching matters for safety, performance, and compliance.

Practical guidance for installation and optimization

• Before ordering, verify the fit and ratings for your specific GE panel or switchgear. The DE365RT part number is the best reference for compatibility.
• Ensure the power is fully de-energized and follow lockout/tagout procedures before installation or replacement.
• Confirm that your system’s voltage and load requirements align with the 600V, 400A, 3-Pole ratings of this plug.
• Maintain a small inventory of GE-approved spare parts, including fusible bus plugs like the DE365RT, to shorten repair windows.
• Work with a qualified electrical professional to confirm clearances, panel interlocks, and any regional code requirements during retrofit or replacement projects.
