Schneider Electric ZB5AC44 Momentary Push-button Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AC44 is a momentary push-button switch operator designed for industrial control panel applications. It features a red, round, extended mushroom-head button in a nonilluminated configuration. The operator mounts through a 22 mm panel cutout and is constructed with a plastic pushbutton body. At 0.08 pounds, it is a compact, lightweight component intended for integration into control stations, machine panels, and operator interface enclosures. Licensed electricians and panel builders typically install this switch as part of a larger control circuit assembly.

The ZB5AC44 is suited for use in industrial and commercial settings where a momentary contact operator is required. Its NEMA 4X and NEMA 13 ratings make it appropriate for environments exposed to dust, oil mist, and washdown conditions. The mushroom-head profile provides a large, easily accessible actuation surface, which is common in emergency-stop or high-visibility control applications on machine panels and process equipment.

Installation Notes

Installation is performed by a licensed electrician or qualified panel builder. De-energize and lock out the control panel before removing or installing any switch operator. The operator mounts through a 22 mm panel cutout and secures with a retaining nut; verify torque is per the enclosure and contact block manufacturer guidelines. Wiring of associated contact blocks must comply with applicable NEC requirements for industrial control wiring.
