Eaton P3BKD3150 Plug-in Circuit Breaker - 65 kAIC
Part Number: P3BKD3150
Quick Summary
Pow-R-Way III circuit breaker plug-in unit protects busway systems in industrial facilities. Installing into complex busway layouts is challenging when grounding options and ratings aren't clearly understood. This model combines a three-pole, K-frame design with a 150A rating and high interrupt ratings across voltage classes, supporting fast, code-compliant protection. It meets ANSI/UL 857, CSA certification and IEEE certification and is NEMA compliant, reducing compliance risk across plant floors. The design is optimized for busway integration, offering reliable protection with a compact form factor to streamline installation, maintenance, and future scalability for critical feeders within modern power distribution schemes. This combination translates to lower lifecycle costs and fewer site surprises.
