The P3BFD3100N uses a three-pole, F-frame Pow-R-Way III design with a 100 A rating and a high interrupt capacity of 65 kAIC at 240 VAC. This feature delivers robust fault protection, reducing arc energy and protecting sensitive downstream equipment, which translates to fewer downtime events in busy production environments and enhanced safety in busway-fed systems. The plug-in format simplifies installation on existing busways, enabling rapid upgrades and easy expansion as plant power needs grow. In practice, this means quicker changeovers, reduced commissioning time, and lower total cost of ownership for three-phase power distribution in manufacturing and logistics facilities.
