For resistive loads (AC-1) it can cycle up to 1 000 ops/h, and for the heavy inrush of AC-4 (plugging/reversing) it's rated 250 ops/h. The S00 footprint — 45 mm wide, 73 mm deep, 58 mm tall — fits tight panel layouts.","metaTitle":"Siemens 3RT2015-4BB42 SIRIUS Contactor, 24 V DC Coil, S00","metaDescription":"Siemens 3RT2015-4BB42 SIRIUS power contactor, Size S00, 24 V DC coil, screw & snap-on DIN rail mounting.
