Width is 55 mm, height 112 mm, depth 115 mm — size S2. Screw terminals accept 2x (0.75…16 mm²) solid/stranded or 2x (0.5…1.5 mm²) fine-stranded with ferrules. Auxiliary contact blocks can be added on top (the contactor has no built-in aux contacts).","metaTitle":"Siemens 3RT5036-1AP20 SIRIUS Contactor, AC-3 22 kW 400 V, 3-","metaDescription":"Siemens 3RT5036-1AP20 SIRIUS power contactor, AC-3 rated 22 kW at 400 V, 3-pole S2, 240 V AC coil.
