SIEMENS 30 mm Selector Switch

The SIEMENS 52SX2CABA2 is a non-illuminated selector switch with a 30 mm mounting diameter and three maintained positions. It uses a black lever operator on a metal body with a zinc die-cast bezel. The contact block provides 2NO/2NC circuits rated at 10A at 600V AC.

Panels needing three maintained positions

This switch suits control panels that require a lever-operated selector with three distinct maintained states and a 2NO/2NC contact arrangement. It is not for applications needing momentary action, key-operated security, illuminated status indication, or a different contact configuration such as 1NO/1NC.

Standard 30 mm panel installation

The switch installs into a standard 30 mm cut-out using the integrated mounting hardware. The plastic operator head and metal construction align with NEMA 1, 3, 3R, 4, 4X, 12 and 13 ratings. Miswiring the XOXO and OOOO cam sequences for positions A and B is the most common error during commissioning.

Questions about this item

What panel cut-out size does the 30 mm selector switch require?

The operator mounts in a standard 30 mm round cut-out; ensure the panel thickness suits the supplied mounting hardware.

Can the 10 A / 600 V AC contacts be wired in series with legacy 5 A pilot devices?

Yes — the 2NO/2NC contacts are rated 10 A at 600 V AC, so they can safely carry the lower current of older 5 A pilot devices.

How do I verify the maintained lever action at each of the three positions after installation?

Move the lever to positions A, B and C; the switch operation codes XOXO (A), OOOO (B) and XOXO (C) should match the contact state shown on the wiring diagram.
