General Electric | DE421R | Fusible Bus Plug | 30A | 4-Pole | 240V

General Electric's DE421R Fusible Bus Plug is a purpose-built solution for maintenance, retrofit, and replacement needs in industrial electrical distributions. With a 30A rating, 4-Pole configuration, and 240V capability, this plug is designed to integrate precisely where matching specs are required, delivering dependable protection and streamlined serviceability.

• Amperage: 30A
• Poles: 4-Pole
• Voltage: 240V
• Type: Fusible bus plug
• Brand/Compatibility: General Electric, DE421R part number as the best reference for compatibility

Why a fusible bus plug matters in your panel or bus duct system: it provides protective fast-acting fusing within the bus assembly, helping to interrupt fault currents and shield downstream equipment from damage. The four-pole design supports multiple circuits or phases in a single plug, simplifying installation and reducing parts variety during maintenance or upgrades.

Ideal use scenarios include:

• Maintenance on GE switchgear or bus duct systems that require a DE421R-compatible plug
• Retrofit projects where existing infrastructure calls for a 30A, 4-Pole, 240V fusible plug
• Replacement when a prior unit reaches end-of-life or exhibits normal wear in critical distribution paths

Important compatibility notes: always confirm fit and ratings before ordering. The DE421R part number is the most reliable reference to ensure a precise match with your equipment’s bus plug connections and protective requirements.

Who benefits most from the DE421R:

• Electrical maintenance technicians working on industrial facilities
• Engineers and project teams performing retrofits or capacity upgrades
• Procurement professionals sourcing authentic GE spares to maintain system reliability

Practical considerations and tips for best results: verify that your bus assembly supports a 4-Pole, 240V fusible plug, and align the 30A rating with the protective needs of the circuit. Store and handle the plug according to standard electrical safety practices, and use it as part of an overall coordinated protection strategy to minimize downtime during service events.

Equip your distribution hardware with the GE DE421R Fusible Bus Plug to maintain reliability, simplify maintenance workflows, and ensure a precise, compatible fit for your 30A, 4-Pole, 240V applications.
