The DC switching capacity is specified at 10 000 operations per hour, and the arcing time sits between 10 and 15 ms. The S00 footprint is compact: 57.5 mm high, 45 mm wide, and 117 mm deep. ## Contact Ratings and Duty The 3RH2353-1CH00-0KA0 provides five NO contacts rated for AC switching across the full voltage range: 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The DC ratings are lower, as expected — 0.5 A at 440 V and 0.26 A at 600 V — so for DC control circuits, verify the load against the specific voltage row. The mechanical life is 10 million operations typical, and the operating temperature span is -25 to +60 °C, with storage from -55 to +80 °C. Compared to the 3RH2362-2AF00, which carries a different contact arrangement (typically 3 NO + 2 NC or similar), this 5-NO variant is the right choice when you need all five poles to make on coil pickup — no break contacts to wire around. The S00 frame and DIN-rail footprint are identical, so a swap between the two requires no panel rework, just a check of the contact configuration against the schematic. The 3RH2353-1CH00-0KA0 carries a RoHS compliance date of 07/01/2006, indicating it meets the original RoHS directive. The brand provides standard Siemens SIRIUS documentation including a datasheet, operating instructions, and a CE declaration of conformity.","metaTitle":"Siemens 3RH2353-1CH00-0KA0 SIRIUS Auxiliary Contactor, 5 NO","metaDescription":"Siemens SIRIUS 3RH2353-1CH00-0KA0 auxiliary contactor, size S00, 5 NO contacts, 10 A at 24 V.
