Square D 9991SDG8 Contactor Enclosure Sdo

Product Description

The SQUARE D 9991SDG8 is a contactor enclosure designed to house and protect SDO series contactors in electrical control applications. The enclosure provides a secure, code-appropriate housing that shields the contactor from environmental exposure and physical damage. Measuring 12.9 inches in length, 8.2 inches in width, and 7.8 inches in height, it offers adequate interior space for the SDO contactor assembly. At 6.84 pounds, it is a solid, purpose-built unit. Licensed electricians and industrial maintenance technicians typically install this enclosure as part of motor control or load-switching panel assemblies.

This enclosure is suited for use in commercial and industrial electrical installations where contactors require a dedicated, enclosed mounting solution. It is commonly installed in mechanical rooms, rooftop equipment panels, and industrial control cabinets. The 9991SDG8 is sold and packaged as a single unit, making it straightforward to order as a direct replacement or new-installation component alongside an SDO contactor.
