3-Pole, 150 A capacity paired with the JDC frame provides precise overcurrent protection for mid-size busway feeders. This configuration improves fault coordination with upstream breakers and reduces nuisance trips, delivering stable operations in demanding environments. Application: Eaton Pow-R-Way III busway installations in manufacturing lines and distribution centers. Interruption ratings of 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 35 kAIC at 600 VAC translate to higher fault tolerance for critical loads. Business impact: equipment and line downtime are minimized during short-circuit events. Application: data centers, chemical plants, and large-scale manufacturing lines requiring strong fault capability. Compliance and certifications—IEEE, CSA, ANSI, and UL 857—with NEMA compliance provide regulatory confidence. Business impact: simplifies procurement and reduces qualification time for project bidding. Application: facilities targeting strict standards, regulated industries, and multinational sites. Compact dimensions and weight—12.36 in depth, 23.26 in height, 6.97 in width, and 47 lb—facilitate space planning and easier handling during installation or replacement. Business impact: faster installs, fewer site recalculations, lower labor cost. Application: retrofit projects in upgraded distribution panels and busway enclosures. 50% internal grounding option and plug-in convenience simplify field wiring and maintenance. Business impact: quick replacements minimize downtime; compatibility with existing Pow-R-Way III components reduces spare-part variety. Application: ongoing maintenance programs in high-demand facilities. Third-party media and datasheet availability support engineering validation and procurement decisions. Business impact: fosters informed selections and risk mitigation. Application: engineering teams performing detailed design reviews.
