This broad pickup range suits installations where control supply stability is uncertain — the coil holds in above 80% of rated voltage (0.8 initial value) and releases below that threshold. Switching frequency depends on the load duty: up to 1,000 operations per hour at AC-1 (resistive), 800/h at AC-3 (squirrel-cage motor starting), 600/h at AC-2 (slip-ring motor), and 250/h at AC-4 (plugging/inching). The AC-3e rating matches the AC-3 maximum at 800/h. Arcing time runs 10 to 20 ms, with make and break times both in the 30 to 55 ms range for AC and DC. ## Panel Integration and Clearances Physical footprint: 114 mm high, 55 mm wide, 174 mm deep. Wire termination for the main contacts accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors. The auxiliary switch is not fitted on this variant (No auxiliary switch), so any add-on block must be ordered separately if needed.","metaTitle":"Siemens 3RT2036-1NP34 SIRIUS Power Contactor, Size S2, 175-2","metaDescription":"Siemens 3RT2036-1NP34 SIRIUS power contactor, Size S2 frame, screw and snap-on DIN rail mount.
