FAQs
Installation begins with confirming busway compatibility and the P3BFDB3110G’s 3-pole, 110A design. Mount the plug-in unit onto the Pow-R-Way III busway per the Eaton installation guide, connect the conductors to the appropriate terminals, and verify grounding per the 50% internal grounding option. Ensure clearance for venting and torque all connections to manufacturer specifications. This approach minimizes mis-wiring and reduces commissioning time while maintaining regulatory compliance for industrial power distribution.
The P3BFDB3110G provides an 18 kAIC interruption rating at 240 VAC and 14 kAIC at 480 VAC or 600 VAC. This means the device is designed to safely interrupt high short-circuit currents up to those limits at the specified voltages. For facilities with mixed voltage requirements, this rating provides a clear design margin and helps protect equipment and personnel without oversizing components.
Yes. The unit’s 3-pole, 110A configuration, together with 50% internal grounding and robust fault current ratings, makes it well-suited for manufacturing environments. Its NEMA compliance and UL/IEEE/CSA/ANSI certifications ensure reliability under continuous operation, while its plug-in design supports fast maintenance and straightforward replacements in busy production lines.
The device is IEEE Certified, CSA Certified, ANSI, and UL 857 listed, with NEMA compliance. These certifications verify electrical safety, performance, and compatibility with standard industrial practices. They streamline procurement processes, support regulatory audits, and reduce risk when designing or upgrading power distribution systems in regulated facilities.
The plug-in unit reduces downtime through quick, reliable field replacement and predictable tripping characteristics, contributing to lower maintenance costs. With standardized dimensions and a well-documented catalog number, spare parts and replacements are easier to source. Regular inspection of connections and grounding integrity, aligned with manufacturer guidelines, helps sustain performance and prolong service life in continuous-operation environments.
