The S00 frame is 45 mm wide, 57.5 mm tall, 117 mm deep — a standard footprint that shares the same cutout as the 3RH2 contactor range. ## Contact ratings and switching performance The 5 NO contacts are rated for AC and DC loads across the voltage range: 10 A at 24 V, 6 A at 230 V AC, 3 A at 400 V AC, 1 A at 690 V AC. DC ratings drop with voltage: 4.7 A at 60 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V. Switching frequency for DC loads is 10,000 operations per hour. AC switching time is 4 to 15 ms. The coil operates at 50 Hz (0.8 to 1.1 x rated voltage) and 60 Hz (0.85 to 1.1 x rated voltage). Wire connection accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded.","metaTitle":"Siemens 3RH2353-1CF00-0KA0 SIRIUS Auxiliary Contactor, 5 NO","metaDescription":"Siemens 3RH2353-1CF00-0KA0 SIRIUS auxiliary contactor, size S00, 5 NO contacts rated 10 A at 24 V.
