Why they are similar
- A6X30140765 shares the same 40mm head size, black color family, and identical technical parameters. The difference is the primary listing explicitly specifies E-Stop, Round; A6X30140765 is listed as Pushbutton, Mushroom. Both require the same contact block family.
- A6X30140761 differs in head color (red). All other catalog fields — size, cutout, series, encapsulation, compatibility — match verbatim. The red color variant serves general-purpose mushroom operator functions where A6X30140768 targets emergency-stop panel positions.
- A6X30140738 carries a 60mm head, which increases the active touch area. Parametric similarity remains high because the panel cutout, 3SU1 series, illumination type, and contact block requirements are unchanged.
Siemens 3SU1 Emergency Stop — product family context
A6X30140768 is the 40mm emergency-stop body in Siemens' 3SU1 modular operator line. The 3SU1 series covers 22mm panel-cutout devices used across industrial control cabinets and machines. Modular construction separates the actuator (mushroom head, pushbutton, selector) from the contact block; both must be ordered and assembled.
The primary part is designated as an E-Stop, Round actuator. This distinguishes it from standard mushroom pushbuttons in the same series — emergency-stop variants in the 3SU1 family are typically twist-to-reset or key-release, but the actuator body alone does not include the reset mechanism; that function is handled by the contact block assembly.
Package is Box. RoHS3 Compliant. Active product status per the catalog records.
Integration notes — selecting the contact block
The actuator body requires contact block(s) from the same 22mm Siemens 3SU1 series. Panel cutout is 22.3mm round. Illumination is not supported on this body.
Key selection dimensions present in the records:
- Panel cutout: 22.3mm (Round)
- Encapsulation: Box
- Compatible series: Siemens, 22mm
The contact block polarity (NO/NC), electrical rating, and terminal type are determined by the block selected, not the actuator body. Ensure the chosen block is rated for the target circuit voltage and current.
FAQ
Does A6X30140768 include a contact block? No — the catalog entry specifies Requires: Contact Block(s). The body ships without contacts; at least one Siemens 3SU1 contact block must be ordered separately.
What head size does A6X30140768 use? The title specifies 40 mm. A6X30140738 in the same series uses a 60mm head, differing in active touch area.
What panel cutout is needed? 22.3mm round cutout, consistent across the 3SU1 22mm series variants in the catalog records.
