Dimensions are 71 mm wide, 85 mm tall, and 101 mm deep — the S0 frame fits standard 35 mm DIN rail enclosures. Each NO and NC auxiliary contact is rated 20 A continuous. The main circuit handles impulse withstand at 6 kV. Switching frequencies reach 1 000 cycles per hour at AC-1 maximum. For DC switching at 24 V, the maximum permissible current is 0.016 A — this is a signal-level rating, not for power DC loads. The contactor is built for AC motor and resistive loads; the DC curve drops sharply as voltage rises.","metaTitle":"Siemens 3RT1526-3BB48-0PA8 SIRIUS Power Contactor, Size S0,","metaDescription":"Siemens SIRIUS 3RT1526-3BB48-0PA8 power contactor, Size S0, 24 VDC coil, 3 NO main contacts, screw terminals, IP20 front, DIN rail mount.
