SIEMENS 22 mm Illuminated Multi-Head Operator
This SIEMENS 3SU1001-3AB42-0AK0 is a 22 mm illuminated multi-head operator designed for industrial control panels. It suits engineers building or maintaining machinery that requires distinct green and red momentary push functions in a single mounting hole. The plastic head and bezel keep weight low while meeting stringent ingress standards. It is not for buyers who need a maintained latching action or a single-button layout.
Panel mounting and wiring considerations
The 22 mm cut-out matches standard industrial panel dimensions, allowing direct replacement of existing operators. Plastic construction means no grounding path through the bezel, so a separate earth connection may be required depending on the enclosure design. Momentary action on both buttons demands correct wiring to the control circuit; miswiring is the most common cause of unexpected behaviour during commissioning. No legend plate is included, so custom labelling must be sourced separately.
Environmental resilience under continuous duty
Rated IP66, IP67, IP69 and IP69K, the operator withstands high-pressure washdown and temporary immersion typical of food-processing or outdoor installations. NEMA 1, 2, 3, 3R, 4, 4X ratings confirm protection against corrosion, windblown dust and water ingress during prolonged exposure. Low-voltage operation limits heating, so contact resistance remains stable over extended cycles. The plastic head resists UV degradation better than many painted metal alternatives.

Questions about this item
How can I confirm the illuminated multi-head operator is functioning correctly after installation?
Press each flush button and verify the green and red illumination responds immediately with momentary action, while the IP66, IP67, IP69 and IP69K seals remain intact.
What components are included with the 22 mm operator and what must be sourced separately?
The package contains the round plastic-head operator with green/red legend; mounting hardware, contact blocks and any wiring accessories are not included and must be purchased separately.
Which version of the 3SU1001-3AB42-0AK0 should I select for a low-voltage panel rated NEMA 4X?
Choose this exact model — it carries NEMA 1, 2, 3, 3R, 4, 4X ratings and low-voltage operation, matching the panel requirements.
