Mechanical endurance is 10 million operations typical — this is a high-cycle auxiliary block suited for frequent valve or contactor pilot duty, not a one-shot isolation device. ## Panel fit — 45 mm wide, S00 frame, DIN rail snap-on Width is 45 mm, depth 117 mm, height 57.5 mm — the S00 frame size fits alongside a standard motor starter or contactor in a crowded control panel without overhanging the rail. ## Wiring and environment — 2 x 4 mm² solid/stranded, pollution degree 3 Relative humidity minimum is 10 % — no condensation limit specified, but the pollution degree 3 rating implies the housing tolerates occasional condensation without tracking. ## Lifecycle and sourcing — current production, no successor on record RoHS compliance date is 07/01/2006 — the part meets the original RoHS directive; verify REACH and UKCA status separately if required for your jurisdiction.","metaTitle":"Siemens 3RH2344-1CH00 SIRIUS Auxiliary Contactor, 4 NO, 10 A","metaDescription":"Siemens 3RH2344-1CH00 SIRIUS auxiliary contactor, size S00, 4 NO contacts rated 10 A at 24 V.
