FAQs
The P3BKW3315GNSP is designed for KW K-frame busways and three-pole configurations, enabling compact mounting in standard panels. Plan for 13.29 in depth, 34.41 in height, and 7.79 in width, ensuring sufficient space for the sprinkler-protected plug-in unit and wiring clearance. Verify neutral and grounding routing (100% neutral, 50% internal ground) to maintain proper fault paths and safe operation.
The 85 kAIC interrupt rating at 220–240 VAC provides robust fault clearance in high-current scenarios common in busway-fed systems. This rating supports improved system safety, reduced arc energy exposure, and enhanced uptime during short-circuit events, particularly in industrial environments where large motor loads are present.
Yes. The P3BKW3315GNSP is designed for KW/K-frame busway configurations and features a sprinkler-proof plug-in design. This compatibility delivers dependable protection in facilities with sprinkler systems, helping to minimize installation changes and extend life cycle performance without compromising safety.
The unit is IEEE Certified, UL 857 listed, and CSA Certified, with NEMA compliance. These certifications confirm adherence to recognized safety and performance standards, supporting regulatory compliance across industrial facilities and facilitating smoother procurement and inspections.
Eaton offers a one-year warranty from installation or eighteen months from shipment, whichever comes first. Maintenance is typically limited to routine inspection of connections, neutrality and grounding integrity, and confirming the sprinkler-proof plug remains sealed and unobstructed to preserve protection integrity and prevent downtime.
