FAQs
Yes. FD907720-4FS is designed to integrate with Eaton B-Line series components, offering a ground mounting method, compatible dimensions, and a 3-point latching system that aligns with standard B-Line enclosure accessories. The 90 in H x 77.75 in W footprint accommodates large panels while maintaining mechanical compatibility with related mounting hardware and knockouts for straightforward wiring.
Key specifications include 90 in height, 77.75 in width, 20 in depth, and a weight of about 992.8 lb. The enclosure is constructed from 12-gauge carbon steel with an oil-resistant gasket and ANSI 61 gray painted finish. It features a hinged cover, large double doors, a 3-point latching handle, ground provisions, bottom knockouts, and defaulter padlock accommodations.
The enclosure is rated for NEMA 12 applications, which supports indoor use and protected outdoor environments where dust and light moisture exposure are present. For fully outdoor use, verify site protections and potential accessory options, but the unit’s rugged construction and gasket sealing provide strong protection in semi-exposed locations and sheltered areas.
The enclosure carries UL 508A and CSA C22.2 certifications, along with NEMA rating 12. These third-party certifications confirm electrical safety compliance, appropriate performance under control-panel conditions, and suitability for industrial power-distribution environments, reducing commissioning risk and helping meet regulatory requirements for many facilities.
The combination of heavy-gauge carbon steel, oil-resistant gasket, and a secure 3-point latch reduces ingress and wear, lowering maintenance frequency. Ground mounting and bottom knockouts simplify wiring changes, while defeater padlock provisions enhance security. Overall, this translates to improved uptime, predictable lifecycle costs, and easier future expansions or reconfigurations.
