ITE/Siemens BOS14353 - 100A, 3-Pole, Fusible Bus Plug

ITE/Siemens BOS14353 Fusible Bus Plug — 100A, 3-Pole — is a purpose-built solution for robust power distribution in demanding industrial and commercial environments.

Designed to work with busway and panelboard distribution systems, this fusible plug provides integrated overcurrent protection at the plug level, enabling fast fault isolation and safer, faster maintenance. The BOS14353 is particularly valuable in retrofit projects and service scenarios where compatible, hard-to-find busplugs are required.

Key specifications

• Amperage: 100 A
• Phase / Poles: 3-Pole (three-phase)
• Type: Fusible Bus Plug
• Application: Busway and panelboard power distribution systems

Where it shines

Industrial plants and commercial facilities rely on reliable power distribution to keep equipment running and processes on schedule. The BOS14353 is built for these environments, offering rugged construction and precise fit within Siemens ITE busway ecosystems. Typical use includes feeding process equipment, distribution panels, and branch circuits that demand dependable protection with minimal downtime.

Why this fusible plug matters

• Integrated protection: The fused plug combines connection and overcurrent protection in one compact unit, simplifying wiring and improving response time during fault events.
• 3-Pole efficiency: Designed for three-phase systems common in industrial and commercial sites, ensuring balanced protection across all phases.
• Retrofit-friendly: A practical choice for maintenance, repair, and upgrade projects—especially when standard, hard-to-find busplugs are needed to match existing infrastructure.
• Easy maintenance: Quick replacement of a failed plug helps minimize equipment downtime and keeps critical lines energized with minimal disruption.

Ideal use cases

Use BOS14353 in scenarios such as:

• Upgrading aging distribution networks in manufacturing floors
• Expanding or retrofitting commercial facilities with protected busway connections
• Supporting process equipment that requires reliable, fuse-protected power feeds
• Spare-part strategy for service teams that manage Siemens ITE busway ecosystems

Practical tips for installation and procurement

• Verify compatibility with your current busway and panelboard model within the Siemens ITE family to ensure proper fit and electrical characteristics.
• Plan for fuse replacement and have compatible fuse elements on hand to minimize downtime during maintenance windows.
• Document the BOS14353 location in your electrical diagrams for faster future servicing and upgrades.
