Eaton P3BKD3150N Plug-in Circuit Breaker - UL 857
Part Number: P3BKD3150N
Quick Summary
Eaton P3BKD3150N is a plug‑in circuit breaker for busway power distribution in industrial switchgear. Installers face challenges delivering reliable short‑circuit protection with equal grounding performance in space‑constrained panels. It carries IEEE Certified, ANSI/CSA Certified, and UL 857 ratings to support compliance and safe operation. Built around the Pow‑R‑Way III design with 100% Neutral and 50% integral grounding, it speeds installation and reduces wiring errors. In practice, engineers can rely on a three‑pole configuration rated at 150A with high interrupt capability (65 kAIC at 240 Vac, 35 kAIC at 480 Vac, 25 kAIC at 600 Vac) for demanding busway circuits. Its dimensions and weight (13.29 in depth, 34.41 in height, 7.79 in width, 53 lb) support straightforward mounting in standard enclosures.
