DFC421 20A, 240V Fusible Lighting Bus Plug

Meet the GE DFC421 20A, 240V Fusible Lighting Bus Plug — a purpose-built protection module designed for commercial and industrial lighting systems. As part of GE’s Lighting LTG series, this plug-in device delivers reliable overcurrent protection while streamlining maintenance and fuse replacements in busy electrical rooms.

What this does for your lighting network
The DFC421 provides a dedicated, fuse-protected path for lighting loads on 240V circuits. Its fusible design helps prevent damage to wiring, ballasts, and related gear during faults, reducing the risk of costly outages and fire hazards. By integrating protection directly into the lighting bus plug, it minimizes downtime and simplifies service when a fuse needs replacement.

• 20A at 240V rating — designed for typical commercial lighting circuits, ensuring a safe, predictable current limit for a wide range of loads.
• Fusible design — built-in fuse provides fast-acting protection, helping to isolate faults quickly and protect surrounding equipment.
• LTG series compatibility — engineered to slot into GE Lighting LTG bus systems for a cohesive, plug-in protection solution.
• Plug-in convenience — streamlined installation and straightforward fuse replacement within compatible bus setups, reducing maintenance time.

Ideal for facilities teams, electrical contractors, and building maintenance crews working with GE LTG lighting installations in offices, retail spaces, theaters, and industrial environments. If your 240V lighting network demands reliable overcurrent protection with quick serviceability, the DFC421 is a fit.

Use cases

• Retrofits and upgrades in existing GE LTG lighting systems requiring a dedicated 20A fused feed for a branch of the circuit.
• New installations that need a modular, plug-in protection point for lighting loads on 240V distribution.
• Maintenance workflows that benefit from rapid fuse swaps without extensive disassembly.

What sets the DFC421 apart from generic fusing options is its seamless integration with GE’s LTG bus architecture. It provides a precise, rated fuse path exactly where lighting loads connect, helping you maintain safer, more reliable circuits with minimal downtime. For anyone building or maintaining a 240V lighting network, this fusible bus plug offers a practical, purpose-built solution that aligns with GE’s trusted Lighting LTG ecosystem.
