Plug enclosure
The P3BLD3600N is a three-pole, four-wire circuit breaker plug-in unit designed for busway power distribution. This configuration delivers precise protection for multi-wire feeders and reduces miswiring during installation, increasing first-pass acceptance in the field. Power protection is quantified by an interrupt rating of 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 25 kAIC at 600 Vac, providing robust fault mitigation for diverse load profiles and helping facilities meet short-circuit withstand requirements without over-sizing equipment. With 100% neutral capability and 50% integral or housing grounding options, the unit supports safe, code-compliant grounding practices while maintaining a compact plug enclosure that simplifies enclosure fill and wiring. The 600 A amperage rating aligns with high-demand busway feeders, delivering scalable protection as facilities expand. This module is designed for easy integration with Eaton Pow-R-Way III busway families, reducing field engineering time and ensuring compatibility across Eaton and third-party components. From an operations perspective, the unit lowers lifecycle costs by standardizing protection modules, facilitating easier maintenance, testing, and replacement in routine preventive programs. In terms of installation, its plug-in design supports modular upgrades and rapid panel reconfiguration, which is especially valuable in manufacturing lines and data-center-adjacent facilities that require flexible distribution solutions. Industry professionals benefit from the combination of strict compliance, predictable performance, and a compact footprint that helps maximize rack and cabinet space while preserving easy access for service and diagnostics. The result is improved uptime, safer operation, and a more efficient path to scalable power distribution in busway environments.

FAQs
The P3BLD3600N is designed for three-pole, four-wire busway configurations with a plug enclosure and 50% integral or housing grounding. Installers should verify 600 V rating, ensure neutral is configured at 100%, and match interrupt ratings to system fault levels (65 kAIC at 240 V, 35 kAIC at 480 V, 25 kAIC at 600 V). Proper torque on connectors and secure mounting within the Pow-R-Way III busway family minimizes thermal and electrical stress, and enables straightforward maintenance access.
Key specs include a 600 A amperage rating, 600 V voltage rating, and interrupt ratings of 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 25 kAIC at 600 Vac. It supports 100% Neutral and 50% Integral or Housing Grounding, making it suitable for high-demand, multi-wire feeders in busway environments while ensuring safe, code-compliant operation.
Yes. The P3BLD3600N carries IEEE Certified, CSA Certified, ANSI, and UL 857 listings, plus NEMA compliance. This combination supports regulatory compliance for industrial installations and provides assurance for utilities, contractors, and facility managers handling rigorous safety and performance standards.
Applications include centralized busway power distribution in manufacturing floors, data-center-adjacent electrical rooms, and large commercial facilities. The unit’s plug enclosure, 3-pole 4-wire configuration, and grounding options enable reliable protection for heavy feeders, while its compact footprint facilitates space-constrained installations and rapid deployment in modular or retrofit projects.
The product follows Eaton’s policy terms, with a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Regular maintenance should include periodic inspection of grounding connections, neutral continuity checks, and verification of tighten torque on connections. This approach supports predictable performance, reduces unexpected outages, and extends service life of busway protection components.
