Siemens BOS14351 - 30A, 3-Pole, Switch

The Siemens BOS14351 is a 30A, 3-Pole switch designed for dependable on/off isolation and precise overcurrent protection in demanding industrial and commercial environments. This compact, maintainable fusible switch delivers fast, clear disconnects when you need them and strong protection when faults occur, helping keep downtime to a minimum.

• Model: BOS14351
• Amperage: 30A
• Poles: 3-Pole

Why this matters in real-world setups:

• Motor disconnects made safe and simple: Quickly isolate three-phase motors during maintenance or fault conditions, reducing exposure and risk for technicians.
• Panelboard integration: Designed to fit into standard enclosures, providing a reliable, accessible isolation point within control panels.
• Targeted branch circuit protection: Localize faults to protect downstream equipment and improve overall system reliability.
• Compact and maintainable: A space-efficient solution that is easier to service than bulkier switchgear, with straightforward access for inspections and fuse-related tasks where applicable.

What makes the BOS14351 stand out

Unlike generic switches, the BOS14351 is purpose-built for rugged environments. Its three-pole construction ensures balanced, reliable isolation across all phases, while the fusible switch design combines control and protection in a single, space-conscious package. The result is a safer, faster path to power continuity and fault containment in demanding applications.
