Schneider Electric ZB5AJ3 3-position Selector Switch Operator

Product Description

The SCHNEIDER ELECTRIC ZB5AJ3 is a 3-position maintained selector switch operator designed for industrial and commercial control panel applications. This operator-only component features a black, non-illuminated round handle head with a 22 mm panel cutout diameter. It uses a maintained (MA) operation type, meaning the switch holds its selected position until manually moved. The plastic bezel construction is shock-resistant and vibration-resistant, and the unit carries IP66 and IP69K ingress protection ratings, making it suitable for wash-down and high-moisture environments. Licensed electricians and control panel builders install this component as part of a complete 22 mm selector switch assembly.

The ZB5AJ3 is used in 22 mm control panel installations across industrial, commercial, and marine environments. Its IP66 and IP69K ratings make it appropriate for food and beverage processing, water treatment facilities, and other applications where high-pressure wash-down or water ingress is a concern. The 3-position configuration is commonly used for hand-off-auto (HOA) or similar multi-mode selector circuits. Because this is the operator head only, it must be paired with a compatible contact block or switch body to complete the assembly.

Key Features

• 3-position maintained operation holds position without spring return
• 22 mm round head fits standard 22 mm panel cutout diameter
• IP66 and IP69K rated for wash-down and high-moisture environments
• NEMA 13 and 4X rated for indoor and corrosion-resistant applications
• Non-illuminated black plastic bezel with shock-resistant and vibration-resistant construction
• Meets UL 508, CSA C22.2 No. 14, EN/IEC 60947-5-1, and multiple international standards

Compatibility

Designed as an operator-only component for 22 mm modular selector switch assemblies. Must be paired with a compatible contact block to form a complete switch unit. No specific compatible contact block or system family was identified in the available product data.

Installation Notes

Installation is performed by a licensed electrician or qualified control panel technician. De-energize and lock out the panel before removing or installing any switch operator. This is an operator-only component and requires a separate contact block rated for the intended circuit. Wiring and panel construction must comply with NEC and applicable local electrical codes.
