The 800 1/h maximum at AC-3 means it can cycle a motor start roughly every 4.5 seconds; the AC-4 maximum of 250 1/h applies for plugging or inching duty, where the contacts break stalled-rotor current. The 6 kV rated surge voltage resistance (impulse withstand) tells you it's suitable for 400 V and 690 V industrial networks without external surge suppression. Pollution degree 3 confirms it's rated for the conductive-dust and condensation environment typical of an unsealed control panel. Dimensions are 112 mm high, 55 mm wide, 115 mm deep — the S2 frame fits alongside other SIRIUS components on the same DIN rail. The coil draws 0.79 W on closing and holds at 0.36 W DC, so the control transformer sizing is modest. The auxiliary contact block is field-addable (product extension auxiliary switch is supported).","metaTitle":"Siemens 3RT7037-1AP00 Contactor S2, 3-Pole, AC-3 690V, Screw","metaDescription":"Siemens 3RT7037-1AP00 S2 contactor, 3-pole, AC-3 rated to 690 V.
