현행 제품Siemens SIRIUS 3SB2 16mm Compact Pushbutton (legacy)
Siemens 3SB2 legacy 30mm push button — predecessor to SIRIUS ACT.
일반적인 용도
Legacy Siemens 30mm button found on older German/European machinery from 1990-2013. Replaced by the 22mm SIRIUS ACT 3SU1 series. Still available for legacy replacement. If you see 3SB on a Siemens panel, these are the buttons.
호환성
Legacy 30mm — not compatible with 22mm SIRIUS ACT. For new builds, migrate to 3SU1 (22mm). 30mm cutout requires adapter plate for 22mm replacement.

설치 빠른 참조
Panel cutout: 16mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

문제 해결
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
