Key points for selecting the "height" and "width" of copper bars to achieve cost reduction.

Selection knowledge for copper bars (main bars and branch bars): Choose standard dimensions for better quality products!

【Before】 The copper bar determines its cross-sectional area (height × width) based on the flowing electrical capacity, but the "height" and "width" that determine the cross-sectional area are fixed combinations of standard dimensions. If the copper bar is designed outside the "height" and "width" specified in the table above, it will deviate from standard products, resulting in increased costs and lead times. ↓ 【After】 Once the required cross-sectional area of the copper bar is determined, the next step is to decide on the dimensions of the copper bar to be used. At this time, even within the standard dimensions (height × width), for a "height" of 3mm, the "width" can be 12mm or 15mm, and for a "height" of 4mm, the "width" can be 12mm, 15mm, or 20mm, allowing for selection from standard copper bar dimensions. This enables cost reduction and shorter lead times for material procurement from the design stage. *For more details, please refer to the catalog or feel free to contact us.*
