3SU1130-0AB70-1BA0

1. Overview

The Siemens 3SU1130-0AB70-1BA0 is a complete illuminated flat (flush) pushbutton from the SIRIUS ACT 3SU1 series, featuring a 22mm round plastic body with metal front ring, black actuator color, momentary (spring-return) operation, and a 1NO (normally open) contact configuration. It belongs to the 3SU1130 sub-family, which is Siemens' plastic-body flat-actuator complete-unit line within the broader SIRIUS ACT portfolio — introduced around 2013 to replace the older 3SB series. SIRIUS ACT is Siemens' flagship industrial command and signaling family, competing directly with Schneider Electric's Harmony XB4/XB5 line and Eaton M22 series.

2. User Sentiment

No independent user reviews or forum discussions specific to this exact part number were located. However, the broader SIRIUS ACT 3SU1 series is consistently described by Siemens and distributors as "quick and easy to install" thanks to its snap-on single-handed installation concept, a differentiating feature for panel builders. The modular plug-in architecture is praised for field reconfiguration flexibility without special tools. No documented quality complaints were found in public channels. The series is an active product with wide distributor availability across North America, Europe, and Asia.

3. Real-World Applications

The SIRIUS ACT 3SU1130 plastic flat pushbutton is used predominantly in general-purpose industrial control panels across manufacturing, machine tools, conveyor systems, and material handling equipment. The IP66/IP67/IP69K protection rating makes it suitable for food and beverage processing (washdown environments), automotive assembly lines (cycle start, test mode, HMI page changes), and process control stations. Black actuator color per IEC 60204-1 signifies no specific safety function — used for reset, test, acknowledge, or any general control function. ATEX-certified variants support deployment in gas and dust hazardous areas (Zone 1/2 for gas; Zone 21/22 for dust).

5. Ordering & Compatibility

The 3SU1130-0AB70-1BA0 is a complete unit; pricing based on similar 3SU1130-series and 3SU1102 plastic variants runs approximately $15–$60 USD depending on distributor and volume — with the metal-body comparable 3SU1152-0AB70-1BA0 listed at ~$119.50 at DigiKey (suggesting the plastic variant is lower cost). Availability is typically on manufacturer lead time (4 weeks) at major distributors including Siemens Industry Mall, Mouser, DigiKey, and RS Components. Compatible accessories include 3SU1400 series contact blocks (1NO: 3SU1400-1AA10-1BA0; 1NC: 3SU1400-1AA10-1CA0) and 3SU1401 LED modules. Up to six contact modules can be stacked on the holder. Related part numbers in same color (black/0AB70): 3SU1102-0AB70-1BA0 (plastic, actuator only or different config), 3SU1152-0AB70-1BA0 (metal body equivalent), 3SU1156-0AB70-1BA0 (metal body with spring-loaded terminals).

6. Known Issues

No significant issues reported for this specific part number in publicly available sources. The 3SU1 series broadly requires separate LED modules for illumination in some configurations — users ordering purely the actuator component without specifying a complete-unit suffix may receive a non-illuminated version; verifying the full part number suffix (1BA0 = complete unit with 1NO) is recommended. Lead times of 4 weeks at major distributors suggest this is a configure-to-order item rather than shelf stock, which can be a consideration for maintenance/repair situations.
