At a Glance

Brand	Siemens
Model	3SU1401-1BB60-3AA0
Product Type	LED module
Core Function	White panel illumination
Application	SIRIUS ACT front-panel signaling

Integrated white illumination

A built-in white LED supplies 900–1400 mcd light intensity for the control-panel indication point.

24 V AC or DC

The same module accepts a rated 24 V AC supply at 50/60 Hz or a 24 V DC supply.

Spring-terminal wiring

Two-conductor connection capability and conductor-specific limits support compact panel wiring.

Product Overview

3SU1401-1BB60-3AA0 provides integrated white LED illumination for SIRIUS ACT front-plate assemblies, with spring-loaded terminals for the control-panel wiring.

Its 24 V AC/DC input suits common control supplies, while the narrow module body supports the modular operator arrangement behind the front plate.

Ordering focus: Select the white, 24 V AC/DC, spring-terminal version and match the front-panel operator and holder to the intended SIRIUS ACT assembly.

Key Functions

Illuminate the panel operator

The integrated white light source provides a defined illumination point within the SIRIUS ACT front-panel assembly.

Use the available 24 V control supply

AC/DC operation permits the same module to work with 24 V DC or 24 V AC at either 50 or 60 Hz.

Connect compact control wiring

Spring-loaded terminals accept bare solid or finely stranded wires and smaller prepared flexible conductors within their specified cross-sections.

Frequently Asked Questions

Can I power 3SU1401-1BB60-3AA0 from either an AC or a DC control supply?

Yes, the integrated LED operates at a rated 24 V DC or 24 V AC at 50 or 60 Hz.

What supply variation can 3SU1401-1BB60-3AA0 tolerate around its 24 V rating?

The permissible operating-voltage tolerance is −30% to +25% relative to the rated 24 V supply.

What should I allow for when switching 3SU1401-1BB60-3AA0 from an electronic output?

Allow for a maximum 2 A inrush current as well as the maximum 25 mA operating consumption when selecting the switching output.

Can I use a 1.5 mm² ferruled wire in 3SU1401-1BB60-3AA0?

No, finely stranded conductors with end preparation are limited to 0.75 mm², while bare solid or finely stranded conductors may be up to 1.5 mm².

Can 3SU1401-1BB60-3AA0 operate in a control enclosure reaching 60 °C?

Yes, 60 °C lies within its −25 to +70 °C operating ambient range, provided condensation is prevented.

Does 3SU1401-1BB60-3AA0 make the complete pushbutton assembly waterproof?

No, the LED module has IP40 enclosure protection and IP20 terminals, so the complete assembly needs its own suitable protection arrangement.

How long is the typical illumination life of 3SU1401-1BB60-3AA0?

The integrated LED has a typical operating period of 100,000 hours.

Compatibility & Ordering Notes

Before ordering 3SU1401-1BB60-3AA0: Match the white light source, 24 V AC/DC supply and spring-terminal connection to the required front-panel assembly, and select the operator and holder that complete the SIRIUS ACT arrangement.

Compatibility Checklist for 3SU1401-1BB60-3AA0

• Match the white LED module to the selected SIRIUS ACT front-panel operator and holder.
• Use a rated 24 V AC/DC circuit within the −30% / +25% supply tolerance.
• Check both output inrush capability and steady operating current.
• Choose the permitted conductor cross-section for the actual wire-end preparation.
