3-Pole, 350 A protection provides scalable capacity for mid- to large-scale industrial busway systems. By plugging into the Pow-R-Way III frame, this circuit-breaker plug-in unit delivers robust overcurrent protection with minimal wiring changes and reduced panel downtime. It’s well suited for manufacturing lines, data centers, and process facilities pursuing modular, upgradable power distribution without compromising reliability. High interruption ratings—65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC—translate to fast fault clearance and equipment protection under fault conditions. The plug-in design minimizes downtime during protection upgrades and component replacements, preserving critical loads and simplifying spare-part strategies. This performance is particularly advantageous in heavy industry environments with demanding fault currents, such as metal fabrication and material handling. Grounding options offer flexibility with 50% internal grounding and 100% neutral configurations to optimize fault paths and safety margins. This arrangement reduces arc-flash exposure during servicing while accommodating complex multi-bus configurations. Operators gain clearer containment of fault energy without compromising system integrity in modular power distribution schemes. K-frame Pow-R-Way III compatibility ensures straightforward installation, repeatability, and predictable performance. The plug-in unit features a compact 13.29 inch depth and a manageable 53 lb weight, easing retrofits in crowded electrical rooms and speeding commissioning. Engineering teams benefit from consistent wiring and documented specifications that reduce field engineering time. Compliances and certifications—IEEE Certified, CSA Certified, ANSI, and UL 857—provide regulatory assurance across critical facilities and regulated industries. NEMA compliance further supports broad compatibility with industrial enclosures and wiring practices. This certification stack simplifies procurement, vendor qualification, and audit readiness while maintaining safety margins in daily operation.

FAQs
Install the P3BKDB3350GN into a compatible Pow-R-Way III busway, using the plug-in interface designed for K-frame frames. Confirm 3-pole, 350 A rating and proper grounding configuration before insertion. Adhere to manufacturer torque specs and recommended clearance to prevent overheating, while ensuring easy access for future maintenance and fast replacement during scheduled downtime.
Fault currents are managed by the unit’s interruption ratings: 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. This enables rapid fault clearance, protects downstream equipment, and minimizes arc energy within the busway. In practice, facilities with mixed voltage supplies benefit from consistent protection across the electrical distribution.
Data centers and manufacturing floors benefit from the P3BKDB3350GN’s compliance and modularity. The unit’s IEEE Certified, CSA Certified, ANSI, and UL 857 listings, plus NEMA Compliant status, support critical facility requirements and simplify vendor qualification. Its plug-in nature reduces downtime during upgrades while maintaining strict safety standards. It also supports scalable power distribution strategies essential for growth.
Procurement and audits benefit from the unit’s certifications and regulatory alignment. The combination of IEEE Certified, CSA Certified, ANSI, UL 857, and NEMA Compliant status provides cross-market acceptance and risk reduction. This makes qualification with major system integrators and utilities straightforward, while supporting ongoing compliance for mission-critical environments. Customers also gain traceability for audits and smoother capital approvals.
From a planning perspective, the P3BKDB3350GN occupies a compact footprint and moderate weight. Its dimensions include 13.29 in depth, 34.41 in height, and 7.79 in width, with a weight of 53 lb, enabling simpler handling and installation in crowded electrical rooms. This helps contractors estimate crane or personnel requirements and reduces installation time.
