DH421R - 30A, 240V, 3-Phase, Fusible Bus Plug

Engineered for reliability in demanding industrial and commercial environments, the DH421R Fusible Bus Plug delivers focused, protected power distribution where it matters most. With a 30A rating, 240V capacity, and a 3-Phase design, this bus plug is built to integrate smoothly with busway and panelboard systems, keeping critical equipment energized while maintaining essential fault protection.

Key Benefits

• Precise electrical protection — integrated fusible design provides fast clear-out of faults to safeguard motors, drives, and process equipment.
• Three-phase efficiency — 3-Phase, 30A at 240V delivers balanced power distribution for larger loads typical in industrial plants and commercial facilities.
• Simple retrofit compatibility — specifically suitable for retrofits, upgrades, and maintenance where compatible, hard-to-find busplugs are required.
• Robust busway and panelboard deployment — optimized for dependable insertion into existing busway and panelboard power distribution systems.
• Durable, field-ready design — built to withstand the rigors of industrial environments, reducing downtime during replacements and upgrades.

Ideal Use Scenarios

• Maintenance, repair, and upgrade projects that need a compatible, readily available fusible bus plug
• Industrial plants upgrading power distribution to consolidate or re-route loads on a 3-phase system
• Commercial facilities implementing new process equipment or expanding existing busway infrastructure
• Retrofit projects where downtime must be minimized and compatibility with existing busways is critical

Installation & Compatibility

The DH421R is designed to slot into established busway and panelboard configurations, delivering a secure, fuse-protected connection. When planning installation, ensure compatible fuse ratings and types match the protected circuit and verify alignment with your facility’s electrical codes and standards. This unit’s 30A, 240V, 3-Phase specifications are ideal for controlled, higher-demand pathways without overloading downstream equipment.

What Sets DH421R Apart

• Hard-to-find compatibility— a practical solution for facilities facing limited availability of suitable bus plugs, helping you complete upgrades on schedule.
• Targeted for power distribution systems— purpose-built for busway and panelboard environments, not a generic plug repurposed for distribution.
• Clear, actionable performance— designed to maintain stable, balanced 3-phase distribution while providing fusible protection to mitigate fault conditions.

For facilities aiming to modernize power distribution with reliable, plug-in protection, the DH421R 30A, 240V, 3-Phase Fusible Bus Plug offers a precise, durable solution that aligns with practical retrofit needs and ongoing maintenance workflows.
