FAQs
Yes. The P3BKD3175G is a three-pole, KD plug-in unit designed for KD busway configurations. It uses a K-frame design and plug-in mounting, simplifying field installation and reducing misalignment risks. When integrating, verify busway dimensions and mounting clearances to ensure a clean, snap-in fit within existing switchgear or distribution cabinets.
The unit is rated for 175A with interrupt ratings of 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. This enables protection for high-current motor loads and power distribution branches. Ensure coordination with upstream devices to maintain selectivity and avoid nuisance tripping during fault events.
Yes. It carries UL 857 certification along with ANSI/IEEE and CSA certifications and is NEMA compliant. These standards support electrical safety, interoperability, and safe operation in regulated facilities. For regulated deployments, verify facility-specific requirements and ensure documentation is accessible for audits.
Dimensions are approximately 13.29 in (L) x 34.41 in (H) x 7.79 in (W) with a weight of around 53 lb. Plan for mounting surface rigidity, busway access, and clearance for cable entry. The compact footprint aids retrofits and space-constrained installations without compromising protection performance.
The product comes with a one-year warranty from installation or eighteen months from shipment, whichever occurs first. This coverage supports defect-related replacement or repair and aligns with Eaton’s selling policy. For ROI considerations, factor in uptime gains, service cycle timing, and availability of replacement parts.
