Switching frequency depends on duty: AC-1 (resistive) allows up to 1 000 operations per hour, AC-3 (motor starting) up to 800 per hour, AC-4 (plugging/inching) up to 250 per hour. Arcing time runs 10–20 ms; make/break times are 30–55 ms for both AC and DC circuits. The auxiliary contact ratings: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V — these are the interrupting limits for the integrated auxiliary switch.","metaTitle":"Siemens 3RT2036-1SP30 SIRIUS Power Contactor, S2, 175-280V C","metaDescription":"Siemens SIRIUS 3RT2036-1SP30 power contactor, size S2, coil 175-280 V AC, screw terminals, MTBF 52 a.
