Home Brands Siemens Siemens SIRIUS ACT 3SU Pushbuttons SIRIUS ACT 3SU is the current Siemens 22 mm command and signalling range: pushbuttons, illuminated buttons, selector switches, emergency stops, indicator lights and the contact and LED blocks behind them. Plastic and metal front rings are both available, and the holder-and-block construction means one door cut-out can be reconfigured without rewiring the panel face.

What to check before ordering 3SU parts are modular — an actuator, a holder and at least one contact or LED block are usually all needed for a working device. Match the LED block voltage (24 V AC/DC vs 230 V AC) to your control circuit. Choose plastic or metal front ring deliberately; they are visually different and priced differently. For emergency stops, confirm the release method your safety concept requires — twist, pull or key. Frequently asked questions Does the 3SU part number include the contact block? Usually not. Complete units exist, but most 3SU part numbers are the actuator only.
Can 3SU replace an older 3SB3 device? Yes for the 22 mm cut-out, but the mounting and block system differ, so the holder and contact blocks must be replaced together with the actuator.
