FAQs
Install the P3KDN400 using the KD frame and plug-in configuration for secure, rapid replacement within busway assemblies. Ensure correct three-phase, three-pole alignment and that enclosure space accommodates the 27.7 inch depth. Verify proper torque on lugs and 100% neutral connections, following Eaton’s installation guidelines to minimize commissioning risk.
The unit carries CSA certification, UL 857 listing, and IEEE/ANSI compatibility, with NEMA compliance. These certifications facilitate code compliance during audits, simplify procurement in regulated facilities, and reduce engineering effort when specifying protected busway distributions for industrial environments.
Yes. The 100% neutral capability ensures balanced current across all phases, reducing neutral currents in busway runs and improving protection coordination. This is particularly beneficial in systems with uneven loading or sensitive equipment, helping maintain voltage stability and safer fault isolation in three-phase distributions.
Yes. Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first, under Selling Policy 25-000. This coverage supports preventive maintenance planning and reduces unexpected repair costs while ensuring access to authorized service and genuine replacement parts.
The KD frame enables standardized, modular plug-in protection for busway systems, simplifying preventive maintenance and spare-parts stocking. This approach reduces downtime during component swaps, enables faster field service, and supports scalable expansion across multiple sites with consistent parts and procedures.
