Square D 9080MH312 Steel Din Rail 12 Inch

Product Description

The SQUARE D 9080MH312 is a steel DIN rail designed for mounting control components such as terminal blocks, circuit breakers, relays, and other DIN-compatible devices inside electrical enclosures and control panels. Measuring 12 inches long, 1.38 inches high, and 0.3 inches wide, this rail conforms to standard 35 mm DIN mounting dimensions. The rail is constructed from steel at 0.04 inches thick, providing a rigid, stable mounting surface. Electricians and panel builders use this type of hardware during enclosure assembly and control panel fabrication to organize and secure modular components efficiently.

This DIN rail is suited for use in residential, commercial, and light industrial electrical control panel applications. It serves as a mounting backbone for terminal strips, motor starters, PLCs, and other snap-on DIN-compatible equipment. The compact 12-inch length makes it appropriate for smaller enclosures or for use as a supplemental rail within larger panel layouts. Mounting holes are provided along the rail for secure fastening to enclosure back plates or sub-panels.

Key Features

• Standard 35 mm profile height (1.38 inches) compatible with DIN-mount components
• Steel construction at 0.04 inches material thickness for rigid, durable support
• 12-inch length suits compact enclosures and supplemental panel layouts
• Mounting hole length of 0.98 inches and mounting hole width of 0.71 inches for secure enclosure attachment
• Sold as a single unit with no minimum order requirement beyond one piece

Compatibility

Designed as a standard 35 mm DIN rail replacement or addition for use with any DIN-compatible control components, terminal blocks, or modular electrical devices in residential and commercial panel enclosures.

Installation Notes

Installation is typically performed by licensed electricians during control panel assembly or enclosure buildout. De-energize and lock out the enclosure before mounting or repositioning any DIN rail hardware. Fasten the rail securely to the enclosure back plate through the provided mounting holes using appropriate hardware. Follow applicable NEC guidelines for panel wiring and component spacing when populating the rail with devices.
