It clips onto the contactor coil terminals and suppresses voltage spikes when the coil de-energises — the LED gives a quick visual check that the suppressor is live. ## Voltage selection — AC and DC ranges The AC/DC designation means the same unit works across both supply types within those bands — no separate AC-only or DC-only variant needed. The varistor design handles repetitive surge energy without degradation over the contactor's service life, provided the coil voltage stays within the rated window. ## Physical fit — S0 frame, clip-on, any position Designed for the SIRIUS S0 contactor size, the suppressor measures 30 mm wide, 19 mm high, and 12 mm deep. It fastens via clip-on mounting directly onto the contactor coil terminals — no additional wiring or DIN-rail space consumed. Mounting position is unrestricted, so the suppressor can be oriented any way the panel layout requires. The multi-unit packaging (ZX90 suffix) indicates it ships in bulk for panel-build or MRO quantities. RoHS compliant with a substance prohibition date of October 1, 2009 — the part meets the EU RoHS directive for restricted materials. Siemens provides the standard declaration of conformity and material data sheets on request.","metaTitle":"Siemens 3RT2926-1JJ00-ZX90 SIRIUS Surge Suppressor, Varistor","metaDescription":"Siemens 3RT2926-1JJ00-ZX90 SIRIUS surge suppressor, varistor with LED, AC 24-48V / DC 12-24V, for S0 contactors.
