Rated at 52 A at 480 V in AC-3 duty, this contactor handles typical three-phase induction motor switching up to that current. Switching frequency reaches 800 operations per hour at AC-3, suitable for moderate-duty cycling on conveyors, pumps, and compressors. The main contact configuration is listed as 18...1, indicating a 3-pole main contact block with one normally open auxiliary contact built in. An auxiliary switch is present, and its ratings span 10 A at 24 V up to 0.3 A at 220 V, covering typical PLC and relay interface voltages. The contactor is rated for use in environments where ambient panel temperature stays within that operating band. The S2 frame measures 114 mm high, 55 mm wide, and 130 mm deep. These spacings are for arc flash and heat dissipation — respect them in the enclosure layout, especially when grouping multiple contactors on a DIN rail. Screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire.","metaTitle":"Siemens 3RT2036-1AG20 SIRIUS S2 Power Contactor, 52 A at 480","metaDescription":"Siemens 3RT2036-1AG20 SIRIUS S2 power contactor. 52 A at 480 V AC-3.
