FAQs
When deploying the PRL4X3173L00C2 in 480/277V systems, ensure adequate cabinet space for its 50.25 inch length, 22 inch width, and 8 inch height. Plan top-feed connections to copper bus bars and verify mounting clearance per UL 67 guidelines. Ensure the indoor location meets NEMA 1 enclosure expectations and allows for service access and future expansion.
Yes. The PRL4X3173L00C2 is designed for top-feed copper bus and three-phase operation, delivering 1200A at 480/277V. This configuration minimizes voltage drop, simplifies feeder connections, and supports dense load distribution. Compatibility with copper bus improves reliability in critical applications like data centers and manufacturing lines.
Key specs include 1200A amperage rating, 480/277V maximum, copper bus, internal interior assembly, and a 50.25 inch L by 22 inch W by 8 inch H footprint. It is used in data centers, industrial facilities, and large commercial buildings requiring high-capacity distribution, reliable indoor protection, and scalable expansion within a single panelboard footprint.
The PRL4X3173L00C2 carries UL 67 certification for panelboard compliance and uses a NEMA 1 rated enclosure for indoor protection. These certifications support safe operation in controlled environments, help meet electrical code requirements, and ease procurement with standards-backed reliability during long-term facility operations.
ROI benefits come from reduced panel counts, streamlined wiring, and faster installations, leading to lower labor costs and shorter outage times. Maintenance is simplified by a robust interior assembly and copper bus with reliable three-phase distribution. Over time, the panel supports scalable capacity, reducing future upgrade costs and minimizing downtime in critical production lines.
