These enclosures are commonly used for larger applications involving motor starters, drives, contactors, and PLCs as well as a wide variety of other electrical and electronic equipment.

Junction Box

Designed for use as surface-mounted junction boxes, service boxes, switch boxes and cutout boxes.

Many of these junction boxes are NEMA 1 and NEMA 3R and include pre-punched knockouts for easier cable entry.

Pushbutton Enclosures

These enclosures offer NEMA 4, 4X, 12 or 4/12 protection and are usually available in wall-mount, floor mount and freestanding versions.

Consoles and Consolets

These enclosures house electrical and electronic controls and/or instruments and typically have HMIs, pushbuttons, switches and other pilot devices and controls where operators can access the devices to control and operate machinery and systems.

Consoles and consolets are heavy duty constructed enclosures that protect contents from dirt, dust, oil and water, and are available in various types including; freestanding consoles, operator consoles, console tops, pushbutton consolets, writing desktops, pedestal and bases.
