Eaton Crouse-Hinds 527B-C1 Junction Box - IP66
Part Number: 527B-C1
Quick Summary
527B-C1 junction box from Eaton Crouse-Hinds is a rugged surface-mount enclosure for 1/2-inch trade-size conduits in industrial settings. Designers often struggle with moisture ingress and corrosion in exposed installations, leading to downtime and inspection failures. It meets IP66 ingress protection and NEC/CEC standards, making it suitable for ordinary/non-hazardous locations while withstanding demanding environments. By combining brass construction with a through-feed layout, this enclosure supports reliable wiring in tight spaces and reduces field wiring retries. The compact 4.5-inch depth and surface-mount footprint simplify installation in control panels and equipment racks, delivering robust sealing and ease of maintenance. This adds value across industrial automation, process, and facilities electrical projects.
