It mounts directly onto S2- and S3-frame contactors (3RT2.3 and 3RT2.4 families) via a clip-on fastener, occupying no extra DIN-rail space. It accepts 24–48 V AC at 50/60 Hz and 12–24 V DC, AC/DC control supply. The LED gives a quick visual that the suppressor is live — useful during commissioning or fault-finding without reaching for a meter. Dimensions are 30 mm wide, 30 mm high, 15 mm deep — a compact block that clips onto the contactor's coil terminals. Mounting position is any orientation. That covers most indoor panel environments without derating.","metaTitle":"Siemens 3RT2936-1JJ00 SIRIUS Surge Suppressor, Varistor with","metaDescription":"Siemens SIRIUS surge suppressor 3RT2936-1JJ00, varistor with LED, 24-48 V AC/50-60 Hz, 12-24 V DC.
