A6X30144178 – Siemens 3SU1 Series Pushbutton Operator
The A6X30144178 follows the Siemens 3SU1 series cataloging convention; the prefix and title together indicate a non-illuminated, 22mm round pushbutton operator requiring separate contact blocks.

This DPST-NO/NC arrangement provides two independent poles—one normally open, one normally closed—within a single operator housing.
Contact and Enclosure Ratings
The 10 A rating applies across both AC and DC circuits. IP66/IP67/IP69K certification covers dust-tight sealing, temporary water immersion resistance, and high-pressure high-temperature washdown compatibility—a combination relevant to food-processing, pharmaceutical, and outdoor enclosures. Life-cycle ratings of 10 million operations for both mechanical and electrical modes reflect typical Siemens industrial switch endurance but do not account for load type, switching frequency, or environmental conditions in any specific installation.
Assembly Requirements
The A6X30144178 is the operator only; the title and specs omit mention of an integrated contact block. A compatible Siemens contact block (3SU1 series) must be ordered separately and snapped onto the operator body. Illumination is not supported by this MPN; green and amber LED modules in the 3SU1 family (A6X30143984, A6X30144632) share the series but are separate illuminator components.
Comparable Siemens 3SU1 Components
All listed alternatives share the 3SU1 series lineage and box packaging. The reader must verify compatibility against their specific installation requirements.
| MPN | Title | Shared Traits | Similarity |
|---|---|---|---|
| A6X30144598 | PUSHBUTTON. BLACK. EXTENDED STRO | Same series, 22mm cutout, non-illuminated, requires contact block | 0.65 |
| A6X30144563 | PUSHBUTTON. GREEN. EXTENDED STRO | Same series, 22mm cutout, non-illuminated, requires contact block | 0.63 |
| A6X30144564 | PUSHBUTTON. BLACK. EXTENDED STRO | Same series, 22mm cutout, non-illuminated, requires contact block | 0.63 |
| A6X30141178 | SELECTOR SWITCH. I>O-II. GREEN | Same series, 22mm cutout, requires contact block | 0.64 |
| A6X30143984 | LED MODULE. GREEN | Same series, green illumination, box packaging | 0.80 |

The black extended-stroke pushbuttons (A6X30144598, A6X30144564) share the non-illuminated operator body category but differ in cap color and stroke length relative to A6X30144178. The green LED module (A6X30143984) carries the highest similarity due to shared series and box packaging, though it is an illumination source rather than a contact operator.
