Eaton P3BLDB3600GN Circuit Breaker Plug-in Unit - UL 857
Part Number: P3BLDB3600GN
Quick Summary
P3BLDB3600GN circuit breaker plug-in unit protects busway power distribution in industrial facilities. Engineers often struggle with space constraints, integration hurdles, and maintaining uptime in demanding installations. UL 857, IEEE Certified, and CSA Certified protections underpin safety and reliability while ANSI performance guidance helps meet codes. Designed for 600 V systems with a 600 A rating, it supports scalable busway protection while reducing wiring and maintenance costs. This aligns with Eaton's focus on modular, plug-in solutions that speed installation and serviceability across multicabinet layouts. With NEMA compliance and 600 V protection ratings, the unit supports safe, code-compliant operation in harsh industrial environments. Expected benefits include improved uptime, reduced field wiring, and a shorter mean time to repair.

FAQs
Installation requires mounting the plug-in unit to the busway segment, ensuring proper alignment with the three-pole four-wire configuration and securing the 100% neutral and 50% internal grounding connections. Follow the Eaton installation guide and verify UL 857 compliance during commissioning. A dedicated output tie-in and fault-sensing integration streamline startup and reduce commissioning time.
The unit provides a 600A amperage rating and a 600 V voltage rating. Interrupt ratings are 65 kAIC at 240 V, 35 kAIC at 480 V, and 25 kAIC at 600 V, supporting high fault currents typical in industrial busway installations while maintaining safe disconnect capabilities.
Yes, it is designed for 600 V systems and offers 100% neutral with 50% internal grounding. This configuration supports stable neutral references for demanding loads and helps meet regulatory grounding practices in large-scale power distribution networks.
The unit carries UL 857, IEEE Certified, CSA Certified, and ANSI certifications. These align the product with widespread electrical safety and performance standards, simplifying code compliance, supplier qualification, and procurement across manufacturing plants and facilities.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever comes first. This policy, combined with durable busway protection and modular plug-in design, reduces downtime costs, lowers maintenance expense, and improves total cost of ownership for industrial power distribution.
