A6X30136884 — Siemens 3SU1 Keylock Switch Body

Siemens 3SU1 Keylock: Parameter Overview

The primary part is a Siemens 22mm key-operated switch body from the 3SU1 series, packaged individually in a box. The device requires contact block(s) to complete an electrical circuit and does not include illumination features. As an active-status catalog entry, it is non-illuminated and is designed for round-panel cutout mounting.

Keylock Selection Criteria for 3SU1 Bodies

Key-operated switch bodies in this series are selector units that mechanically define a throw pattern and rest position via internal cam geometry. The A6X30136884 carries the O.M.R. (likely O→I) cam designation, indicating a specific sequence of maintained positions. Key lock variants in the 3SU1 family support different cam configurations that determine throw count and locking positions; the reader's application determines whether O→I→O or other patterns are required.

• Actuator type: Keylock — provides intentional, keyed operation; not a pushbutton or toggle
• Contact block dependency: This body does not include contacts; the catalog specifies that Contact Block(s) are required separately
• 22.3mm round panel cutout: Standard 22mm industrial mounting; verify that enclosure thickness and bezel clearance accommodate the 3SU1 bezel profile
• Non-illuminated: No lamp or LED provision in this body variant
• Series consistency: All 3SU1 bodies share the same 22mm dimensional envelope, which aids standardization across mixed switch types on a panel

Catalog Comparison: 3SU1 Keylock Bodies

The table below presents in-catalog peers sharing identical parameter values for series, panel cutout, illumination, encapsulation, and contact block requirement. These are catalog-similarity entries, not OEM-endorsed substitutes; the reader must qualify any selection.

All listed variants are Siemens 3SU1 bodies sharing the same 22mm panel cutout, box encapsulation, non-illuminated design, and contact-block requirement. They diverge in two dimensions: key lock type (O.M.R., RONIS, BKS) and cam pattern (O-I, I>O-I, I-O<II, I>O<). The O.M.R. entries appear to share the same manufacturer-supplied lock cylinder as A6X30136884.

• A6X30136881 (similarity 1.00) matches the same O.M.R. cam designation but presents an O-I sequence rather than the I>O< of the primary; it shares all other catalog parameters exactly.
• A6X30136874 and A6X30136871 (similarity 0.96) substitute a RONIS lock brand while retaining the O-I cam pattern.
• A6X30136864 (similarity 0.96) uses a BKS lock with a three-position I-OO< of the primary.
• A6X30136803 and A6X30136800 (similarity 0.96) are RONIS-locked with a three-position I>O-I cam.

FAQ

What panel cutout does A6X30136884 require? A 22.3mm round cutout, consistent with the Siemens 22mm switch series.

Does A6X30136884 include contact blocks? No — the catalog entry specifies that Contact Block(s) are required and must be ordered separately to complete the switch assembly.

Can a 1.00-similarity alternate be used as a drop-in replacement for A6X30136884? A6X30136881 shares all catalog parameters with similarity 1.00 but uses the O-I cam pattern instead of the I>O< pattern of the primary. The cam pattern defines the throw sequence, so functional interchangeability depends on whether that sequence matches the application requirement.
