At a Glance

Brand	Siemens
Model	3SU1400-1AA10-3BA0
Product Type	Contact module
Core Function	Operator-actuated circuit switching
Application	SIRIUS ACT front-panel controls

Normally open switching

One NO contact closes the control circuit when the associated operator actuates it.

AC and DC control duties

Use the utilization-category current rating that corresponds to the load and circuit voltage.

Compact spring connection

The 9.8 mm wide module accepts bare or prepared conductors within distinct terminal limits.

Product Overview

3SU1400-1AA10-3BA0 adds one normally open contact to a SIRIUS ACT front-panel operator, using spring-loaded field terminals.

The module fits front-plate arrangements in plastic or metal enclosures and supports AC/DC control circuits with voltage-dependent utilization ratings.

Ordering focus: Select the 1 NO, spring-terminal version and size the switching duty by utilization category rather than thermal current alone.

Key Functions

Switch a normally open control path

The single NO element provides an actuated control contact for the selected SIRIUS ACT operator.

Match the electrical switching duty

AC-15 ratings range from 6 A at 24–230 V to 1.4 A at 500 V, while DC-13 ratings depend on the DC circuit voltage.

Wire a modular front-panel assembly

Spring-loaded terminals support the compact module arrangement behind the front plate.

Frequently Asked Questions

Can 3SU1400-1AA10-3BA0 provide a normally closed stop contact?

No, this module contains one normally open contact and no normally closed contact.

Can I switch a 230 V AC control load with 3SU1400-1AA10-3BA0?

The AC-15 rated operational current is 6 A at 230 V, so the connected control load must remain within that duty rating.

Is the 10 A thermal rating of 3SU1400-1AA10-3BA0 also its 24 V DC inductive switching rating?

No, its DC-13 rated operational current at 24 V is 3 A, while 10 A is the conventional thermal current.

Which conductor limit applies to prepared flexible leads on 3SU1400-1AA10-3BA0?

Finely stranded conductors with end preparation are limited to 0.25–0.75 mm², compared with 0.25–1.5 mm² for bare solid or finely stranded wires.

Can 3SU1400-1AA10-3BA0 be incorporated into both plastic and metal enclosures?

Yes, the contact module is suitable for integration in either plastic or metal enclosures.

How frequently can I operate 3SU1400-1AA10-3BA0 in a repetitive control application?

The maximum operating frequency is 3600 operations per hour.

Does 3SU1400-1AA10-3BA0 provide positive opening for a safety contact function?

No, the normally open contact module does not provide a positive-opening function.

Compatibility & Ordering Notes

Before ordering 3SU1400-1AA10-3BA0: Pair the single NO module with the appropriate SIRIUS ACT operator and holder, retain the spring-terminal connection and check the AC-15 or DC-13 rating for the actual load.

Compatibility Checklist for 3SU1400-1AA10-3BA0

• Select 1 NO where an actuated closing contact is required.
• Match the front-panel operator and module holder.
• Size the load using its utilization category and voltage.
• Keep prepared finely stranded leads within the 0.75 mm² maximum.
