Frequently Asked Questions
1. What is the Siemens 3SU1400-1AA10-3DA0 used for?

It is a 2NO (2 normally open) contact module within the Siemens SIRIUS ACT 3SU1 series. It mounts behind a 22 mm pushbutton, selector switch, or pilot light actuator to provide electrical switching contacts for industrial control panels.

2. What does "2NO" mean?

2NO means two normally open contacts. In the resting state the circuit is open; when the button is pressed the contacts close, allowing current to flow. There are no NC (normally closed) or changeover contacts in this module.

3. What wire sizes can I use with the spring terminals?

The cage-clamp (spring-loaded) terminals accept 0.25–1.5 mm² solid wire, 0.25–0.75 mm² ferruled wire, or AWG 24–16. No screwdriver is required — simply push the wire in.

4. What is the difference between 3SU1400-1AA10-3DA0 and 3SU1400-1AA10-1DA0?

Both are 2NO contact modules in the same series. The difference lies in the terminal type and internal coding — always verify the full part number against your bill of materials or existing panel drawings before ordering.

5. What is the operating temperature range?

−25 °C to +70 °C during operation; −40 °C to +80 °C for storage. Suitable for most industrial indoor environments.
