HESC1063N - 100A, 480/277V, 3-Phase, Fusible Bus Plug

Introducing the HESC1063N Fusible Bus Plug—a purpose-built solution for reliable power distribution in demanding industrial and commercial environments. With a 100A rating and a 480/277V 3-phase capability, this bus plug slips into your existing busways and panelboards to provide targeted, protective fusing right where you need it.

• Model: HESC1063N
• Type: Fusible Bus Plug
• Amperage: 100A
• Voltage Rating: 480/277V
• Phase / Poles: 3-Phase
• Application: Busway and panelboard power distribution systems
• Typical Use: Industrial plants, commercial facilities, process equipment, retrofit projects

This listing is ideal for maintenance, repair, and upgrade projects where compatible, hard-to-find busplugs are required. The HESC1063N is engineered to withstand the rigors of busy electrical rooms and to fit within standard busway footprints, helping you maintain safe, uninterrupted power distribution.

• Targeted protection for 3-phase circuits: 480/277V systems receive appropriate fusible protection where it matters most.
• Plug-and-play reliability: Designed to integrate with common busway and panelboard configurations for quick commissioning.
• Inventory-friendly: A widely compatible 100A fusible option reduces the need for custom replacements in critical facilities.
• Maintenance-friendly: Facilitates upgrades and retrofits without reconfiguring upstream protections.

Ideal for electrical maintenance teams, contractors, and facilities managers responsible for safety and uptime in industrial plants and commercial facilities. It also suits retrofit projects where an exact 3-phase, 100A fusible plug is required to match existing protection schemes.

Compared to alternatives that may offer misaligned ratings or non-fusible options, the HESC1063N ensures proper overcurrent protection within 3-phase 480/277V systems, helping you avoid compatibility gaps during upgrades. Before installation, verify that your busway or panelboard supports a 100A, 480/277V, 3-phase fusible plug, and keep a spare on hand for rapid maintenance cycles.
