These bus plugs provide flexible, quick access points throughout the Siemens busway, providing efficient power distribution across the system without requiring significant changes. This design guarantees that BOS bus plugs connect easily, increasing operating efficiency while reducing installation issues described in the Siemens BD busway installation manual.
BOS Plugs Power Ratings and Bus Duct Disconnect Options
BOS-style bus plugs are available in amperage rates ranging from 400A to 800A and will work with voltages including 240V and 600V. These bus plugs come in fusible and non-fusible designs, providing flexibility for a range of safety and operational requirements.
The Siemens bus duct disconnect function on these bus plugs has safe, on-demand disconnections, critical in applications requiring regulated power changes.

Grounding and Protection from Electrical Power Failures
Some BOS models, like the BOS16425G1 (“G” indicates grounding), contain grounding components to improve electrical protection. These grounded bus plugs add a layer of safety in industrial applications with high power demands, lowering the danger of electrical malfunctions and improving system dependability. Grounding options in the Siemens BD busway collection give alternatives for facilities needing more electrical protection.
Flexible Bus Plug Installation, Relocation, Replacement
With a modular, plug-and-play design, BOS-style bus plugs are easy to install, relocate, or replace along the Siemens BD busway as power requirements evolve. This adaptability is helpful in facilities with high turnover or flexible layouts. Using BOS bus plugs with the Siemens busway tap box gives quick, customizable configurations without extensive rewiring, so you get power access where needed.
Siemens BOS Style Plug for High Power Loads
The standard Siemens BOS design follows Siemens’ stringent technical requirements, providing consistent, dependable performance across many busway installations. Each BOS bus plug is designed to withstand high power loads, increasing the lifespan and safety of the BD busway Siemens system. This consistency provides the dependable functioning described in the Siemens BD busway brochure and installation instructions.
Air-Insulated Busway Stops Overheating, Improves Energy Efficiency
Siemens BD Busway’s air-insulated busway, made of sturdy aluminum casing, offers a cost-effective, high-capacity power distribution solution for buildings, extending its operating life and reducing maintenance and operational expenses.
The air-insulated design improves heat dissipation, preventing overheating and increasing energy efficiency by lowering power loss. This not only adds to constant performance and longer component life but also leads to lower energy costs and a lower carbon impact over time. The Siemens BD Busway’s energy-efficient qualities make it a long-term alternative for establishments looking to save operating and environmental expenses.
