Eaton P3BKDC3150G Circuit Breaker Plug-in - IEEE CSA UL 857

Three-pole plug-in unit with a K-frame design provides rugged protection for busway installations, aligning quickly with minimal toolkit. The plug-in approach reduces field terminal connections, lowers installation time, and minimizes human error during assembly. This translates into shorter commissioning windows, less on-site disruption, and a smoother expansion path when adding new feeder sections within a live production line. The solution also supports standardized testing procedures and predictable maintenance routines by consolidating protection into a single modular unit. With a 150A amperage rating and high interrupt capability—200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 50 kAIC at 600 Vac—the device delivers immediate fault clearance for critical loads. This protects motors, drives, and instrumentation while improving coordination with upstream protective devices. In practice, engineers can confidently scale power distribution without overrating downstream equipment or sacrificing reliability during peak demand. The architecture also enables straightforward integration with existing Eaton control schemes and busway accessories. 50% Internal Grounding supports a reliable fault path inside the unit, reducing the need for extended external grounding schemes in tight enclosures. This feature simplifies panel layout in cramped spaces and enhances EMI performance in manufacturing cells with dense equipment. The grounding option also supports safer maintenance work by ensuring predictable fault paths during testing. For retrofit projects, it enables faster updates without reworking the grounding strategy across an entire panel. Compliance and certification are baked in: UL 857, IEEE certification, CSA certification, and NEMA alignment. This mix of standards simplifies supplier audits, speeds procurement, and helps meet project specs for automotive, food & beverage, and general manufacturing environments. By choosing a unit that aligns with these requirements, panel builders reduce rework and boost design confidence across the lifecycle of the installation. The product’s documented certification trail also streamlines commissioning tests and regulatory reviews. Physical attributes support install planning: dimensions of 13.29 in depth, 34.41 in height, and 7.79 in width, with an approximate weight of 53 lb. The busway-ready footprint and plug-in interface enable modular expansion and straightforward replacement, while the unit’s robust construction withstands industrial environments. Warranty coverage follows Eaton’s policy—one year from installation or eighteen months from shipment—ensuring a defined service window and predictable maintenance budgets, a key consideration for maintenance managers and spec writers alike.
