The 24 VDC coil draws 7.8 VA at 50 Hz and 0.24 VA at 60 Hz, with an operating time of 13 to 25 ms and an arcing time of 10 to 15 ms. For AC loads, the contactor is rated at 230 V, 6 A and 400 V, 3 A, which covers typical motor and heater circuits in control panels. The auxiliary contacts are rated 25 A per NC and NO contact, so they can handle interlocking or pilot-duty loads without an extra relay. The main circuit impulse withstand is 6 kV, matching standard industrial isolation requirements for 400 V class panels. The S0 size is a common footprint for motor starters and small contactors in IEC panels. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, and altitude up to 2000 m without derating.","metaTitle":"Siemens 3RT1526-1AH00 SIRIUS Power Contactor, S0 Size, 24 VD","metaDescription":"Siemens 3RT1526-1AH00 SIRIUS power contactor, S0 size, 24 VDC coil, 10 A rated at 24 V.
