3SU12506KB101AA0

Overview

The Siemens 3SU1250-6KB10-1AA0 is a compact acoustic signaling device from the SIRIUS ACT series. It features a 22 mm round metal housing in black. The unit emits a continuous tone at 2.4 kHz. It provides IP40 protection against dust and water ingress. The device operates on a 24 V supply voltage. It is designed for industrial environments requiring clear auditory status indication.

Feature Summary

• Compact metal construction for durability
• Continuous tone acoustic signaling
• Standard 22 mm panel cutout compatibility

Applications

• Industrial machine status indication
• Process control system alerts
• Factory automation auditory warnings

Procurement Notes

Verify the complete part number including suffixes to ensure correct voltage and tone specifications. Confirm that the required mounting hardware is included or ordered separately, as some variants are sold without holders. Check for specific environmental certifications if the installation area requires explosion-proof ratings, as this model is not certified for hazardous zones.

Selection Notes

Select this component when a durable metal indicator is preferred over plastic alternatives. Ensure the application environment does not exceed the IP40 rating requirements. Verify that the 2.4 kHz continuous tone is appropriate for the ambient noise levels of the target installation site compared to pulsed or variable tone options.

Part Context

This model belongs to the Siemens SIRIUS ACT product line, which focuses on sustainable engineering practices. The series emphasizes extended product life cycles and low-carbon manufacturing processes. It integrates with standard industrial control panels using common 22 mm mounting dimensions for easy retrofitting.

Replacement Considerations

Direct substitutes include other Siemens 3SU1250 series acoustic devices with matching voltage and tone characteristics. Cross-brand replacements require verification of mechanical dimensions and electrical interface compatibility.
