The auxiliary contacts are rated 20 A per NC and per NO contact, giving you headroom for control-circuit interlocking. The contactor accepts solid or stranded conductors up to 2x 2.5 mm² on the main circuit, and the screw-type terminals are standard for panel wiring. The mounting position allows vertical surface rotation of ±180° and tilting of ±30° front-to-back, which simplifies panel layout when rail orientation isn't perfectly vertical. Front face IP20; terminal area IP00. Dimensions are 85 mm high, 71 mm wide, and 101 mm deep — the S0 frame size fits standard 35 mm DIN-rail spacing with room for auxiliary contact blocks on the side. Arcing time 10 to 15 ms; DC switching time 13 to 40 ms. Coil holds at 24 VDC nominal; initial value 0.8, full-scale value 1.1. For DC loads at higher voltages, the rated current drops: 2 A at 60 VDC, 1 A at 110 VDC, 0.3 A at 220 VDC. At 440 VAC it's rated 1 A. These curves are typical for DC switching where arc extinction is more challenging.","metaTitle":"Siemens 3RT1526-3BB48-0PA7 SIRIUS Power Contactor, S0, 24 VD","metaDescription":"Siemens SIRIUS 3RT1526-3BB48-0PA7 power contactor, size S0, 24 VDC coil.
