Siemens A6X30138335 — 22mm Pushbutton Operator, Round, Non-Illuminated

Engineering Verification Checklist

When screening A6X30138335 for a new panel build or retrofit, the following items represent neutral points of confirmation. Each requires the specifying engineer's own qualification against the specific installation conditions.

• Control-circuit voltage matches the contact block coil or supply rating
• Required contact block type (NO/NC) and quantity are defined before ordering
• Panel thickness is within the holder's clamping range for the 22.3mm cutout
• Operator spacing in the enclosure allows the stated 22.3mm round cutout and any required clearance
• Non-illuminated actuator selected — no lamp or LED block is required or compatible at this actuator position
• RoHS3 compliance is confirmed as required for the destination market
• Mechanical latching or momentary-return behavior is coordinated with the process function
• Selector-key or tooled actuation is specified if unauthorized operation must be prevented

Overview

The A6X30138335 is a front-panel operator in Siemens' 22mm modular signaling device family (Series 3SU1). It occupies a single 22.3mm round panel cutout and provides a momentary-contact pushbutton interface. The operator head accepts separately ordered contact blocks (not included) that perform the actual electrical switching.

This unit is packaged individually (Box) and carries an Active product status with ROHS3 compliant marking. It is non-illuminated, meaning no internal lamp or LED circuit is provided at the actuator level.

Key Parameters

Similar Catalog Parts

The table below presents in-catalog rows with shared specification anchors. These are parametric peers for screening purposes only; none constitute an interchange approval or substitute for the user's own qualification.

Why they appear similar: All share the Siemens 3SU1 22mm series, the same 22.3mm round panel cutout, the same non-illuminated construction, and the same requirement for separately ordered contact blocks. They differ in actuator color and in one case in head geometry (oval dual pushbutton vs. round single pushbutton). The color variants carry identical specifications to the primary part aside from the operator cap color.

Family Context — Siemens 3SU1

The 3SU1 series covers a range of 22mm panel-mount operators including pushbuttons, selector switches, pilot lights, and combination units. Part numbers in this series typically encode the operator type and color in the final digit group. Ordering requires selecting the operator head (the item covered here) and then selecting compatible contact blocks (available in screw-clamp or spring-clamp styles) that snap onto the rear of the operator.

FAQ

What is the switching function of the A6X30138335 pushbutton?

The operator head itself does not perform switching. It requires one or more contact blocks (ordered separately) that mount to the rear and define the NO/NC function and electrical ratings.

Can the A6X30138335 be used in an illuminated configuration?

No. This specific part number is non-illuminated and has no provision for a lamp or LED at the actuator. If illumination is required, a different head type in the 3SU1 series would need to be selected.

Are the color variants A6X30138313, A6X30138363, and A6X30138302 electrically identical to the primary part?

Yes, in terms of actuator type, cutout, series, illumination type, and contact-block interface. The only difference is the operator cap color. The user should verify that the selected color aligns with the applicable operator-color standard or plant marking convention for the specific application.
