Schneider Electric ZB5AJ5 3-position Momentary Selector Switch

Product Description

The SCHNEIDER ELECTRIC ZB5AJ5 is a 3-position momentary selector switch operator designed for use with 22 mm modular push-button and selector switch assemblies in industrial control panels. The black, non-illuminated round handle operates with a momentary (MO) action, returning to center after each selection. The plastic bezel is rated IP66 and IP69K, making it resistant to water ingress, shock, and vibration. This operator is installed by licensed electricians and industrial controls technicians in applications where panel-mounted operator interface components require environmental protection.

This selector switch operator suits industrial and commercial control panel applications where a 22 mm mounting hole is required. Its NEMA 4X and NEMA 13 ratings make it appropriate for wash-down environments, food processing facilities, outdoor enclosures, and other locations demanding high ingress protection. The momentary 3-position configuration is commonly used for jog-forward, stop, and jog-reverse control circuits or similar multi-position momentary switching functions.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local electrical codes. De-energize and lock out the control panel before mounting or replacing any operator component. The 22 mm cutout should be verified against the enclosure specification before installation. Do not exceed the ingress protection rating of the mating enclosure, as the operator rating alone does not guarantee system-level protection.
