Siemens A6X30137681 — Pushbutton Operator, 22 mm, Green

Overview

A6X30137681 is the green variant within the Siemens 3SU1 series of round pushbutton operator bodies. The data source lists a 22.3 mm panel cutout, non-illuminated operation, and a mandatory requirement for separate contact blocks (sold and applied after the operator). No electrical ratings (voltage, current, dielectric strength), mechanical life cycles, IP / NEMA environmental protection class, operating temperature range, or actuator travel / force values were supplied in the catalog fields.

Key parameters (from catalog fields)

What the catalog does not specify

Verification required before selection. The following safety-critical and application-critical fields are absent from the supplied data and must be confirmed against the Siemens 3SU1 datasheet before any design commit or procurement:

• Maximum switching voltage and current (for both the contact blocks and the operator itself)
• Dielectric withstand rating
• Mechanical and electrical endurance (operations)
• IP / NEMA protection class for the front-of-panel seal
• Operating temperature range
• Actuator travel, actuation force, or detent feel
• Button material (plastic / metal), color shade code, or surface texture
• Mounting method detail (snap-fit, threaded collar, front-removable)

Integration notes

The operator body alone does not form a functional switch. A complete switching function requires:

1. One or more Siemens contact blocks (3SU1 1NY / 1NO types, etc.) that snap or screw onto the rear of the operator.
2. A compatible 22.3 mm round panel cutout — slightly larger than the 22 mm nominal form factor.
3. Front-panel mounting depth to be verified against the combined operator + contact block stack length.

These details are not specified in the supplied catalog fields; Siemens 3SU1 assembly instructions and contact block datasheets provide the geometry and torque requirements.

Ordering-code / family context (verify on datasheet)

Siemens industrial pushbutton operators use ordering codes that encode product type and color. The prefix A6X30137 identifies the family/series; the trailing digits encode the color variant (green for 681 per observed alternates). Field verification on the official Siemens ordering guide is recommended to confirm this interpretation, as catalog title strings alone do not constitute a formal decoding table.

Similar catalog parts

All alternates belong to the same Siemens 3SU1 series and share identical spec keys. Only color distinguishes them.

Why they are similar: All eight listed MPNs share the same actuator type, illumination mode, series, panel cutout dimension, and contact-block dependency. The similarity scores distinguish MPN edit-distance differences (trailing digit variants) rather than performance or quality differences. Color selection is the sole differentiator.

FAQ

Q: Does A6X30137681 include contact blocks in the same package? A: No — the catalog fields explicitly list Requires: Contact Block(s), meaning the operator body ships without contacts and they must be ordered and installed separately.

Q: Can any 3SU1 contact block be used with A6X30137681? A: The data source confirms compatibility with the Siemens 22 mm 3SU1 series but does not specify which contact block types (NO / NC / dual-throw), rated current, or voltage are compatible. The Siemens 3SU1 contact block datasheet must be consulted to confirm mechanical fit and electrical rating.

Q: Is the green color of A6X30137681 the same shade as A6X30137011? A: The catalog titles list both as "PUSHBUTTON. GREEN," but the MPNs differ in the trailing digits (681 vs. 011), suggesting potential shade or surface variants. The data source does not include color shade codes or RAL references; confirm with the Siemens color chart or sample request if shade matching matters.
