Siemens SIRIUS S2 power contactor in the 3RT2036-3AK60 configuration, built for motor switching on 35 mm DIN rail. Operating range -25 to +60 °C suits refrigerated or heated plant floors; storage holds -55 to +80 °C for spares.
Switching duty and thermal limitations
Rated for 800 operations per hour at AC-3 (motor switching) and 1 000 ops/h at AC-1 (resistive). AC-4 (plugging/inching) caps at 250 ops/h — stay within the lower cycle rate for high-inertia loads where the arcing time (10–20 ms) accumulates heat. The 10 million typical mechanical life means the coil spring and contacts outlast most line life; you'll replace the panel before the contactor wears out.
Active production, standard BOM line
