3SB3000-0AA21 — Siemens SIRIUS 3SB3 Pushbutton & Pilot Device
Siemens SIRIUS 3SB3 is the standard pushbutton and pilot device range for industrial control panels, operator stations, and machine control desks across Saudi Arabia's manufacturing, process, and infrastructure sectors. The 3SB3 family covers the complete set of front-panel operator interface elements: momentary pushbuttons, latching pushbuttons, illuminated pushbuttons with integrated LED, selector switches, key-operated switches, indicator lamps, emergency stop devices (EN ISO 13850 compliant), and pillar light columns — in 22.3 mm round panel cutout for compatibility with the worldwide standard industrial panel cutout size.
The 3SB3's die-cast zinc or plastic actuator bodies with IP65 sealing from the front face withstand Saudi industrial environments including oil & gas facility outdoor control panels, dusty cement factory process areas, and washdown food processing control panels. IP67 and IP69K versions are available for demanding washdown applications. LED illuminated versions operate on 24 V DC directly from PLC output modules with operating life exceeding 100,000 hours — effectively maintenance-free illumination over a panel's 20-year service life.
In Saudi Arabia, 3SB3 pushbuttons are specified for motor control panel operator interfaces, MCC door-mounted start/stop/reset controls, emergency stop stations at machinery and process areas, and manual operator stations at HVAC and water treatment plants. The emergency stop variant with positive-opening contacts per IEC 60947-5-5 satisfies EN ISO 13850 requirements for emergency stop applications.
Razz Middle East stocks SIRIUS 3SB3 pushbuttons and pilot devices in all colours, functions, and contact configurations throughout Saudi Arabia.

Key Features & Benefits
- Complete family covering all operator interface element types from momentary pushbuttons through to E-stop devices and indicator columns standardises on a single 22.3 mm cutout size across the entire panel.
- IP65 front sealing withstands industrial dust, water jets, and oil mist in Saudi outdoor and process area control panel installations.
- LED illumination at 24 V DC with 100,000-hour life provides maintenance-free indicator lamp operation over a 20-year panel service life.
- Emergency stop variant with positive-opening contacts per IEC 60947-5-5 satisfies EN ISO 13850 requirements for emergency stop function at machinery and production line installations.
- Modular contact block system allows the contact configuration of an installed button to be changed in the field by swapping the rear contact block without removing the actuator.
- Key-operated selector switch variant prevents unauthorised mode changes at Saudi industrial machine operator stations where access must be restricted to qualified personnel.
- IP69K variants for food processing areas withstand 80°C high-pressure steam cleaning required between production batches.
Industrial Applications in Saudi Arabia
- Motor starter panel door-mounted start, stop, and reset pushbuttons at industrial facilities, providing the standard operator interface for manual motor control on MCC panels.
- Emergency stop stations at Saudi manufacturing machine line positions, conveyor belt stations, and process area manual shutdown points.
- Illuminated start confirmation indicators on large motor starter panels at ARAMCO and SABIC process plants, providing visual confirmation of motor running state.
- MCC operator station panels for NWC pump station manual start/stop control, where IP65 front sealing provides protection in humid pump station environments.
- HVAC control panel operator interfaces at commercial building plant rooms, where selector switches control AHU mode and pushbuttons control individual fan and pump starts.
- Machine tool operator panels at Saudi precision manufacturing facilities, providing the complete machine operator interface with illuminated mode-select, E-stop, and cycle-start.
- Food processing line operator stations and washdown control panels, where IP69K steam-resistant pushbuttons withstand Saudi food safety regulation cleaning protocols.
