It sits between the AC supply and the drive input, limiting current rise during commutation and smoothing the voltage waveform. The 1.2 mH inductance at 22.5 A rated current (25 A maximum, 31 A peak) is sized for a 3-phase 500 V AC line at 50 Hz. ## Mounting and connection IP00 protection class means no enclosure — mount this inside a panel or cabinet with adequate clearance. Dimensions are 0.178 m wide, 0.153 m high, 0.105 m deep, so plan for a footprint roughly 180 mm × 155 mm on the backplate. Thermal class B (130 °C) insulation per IEC 60085, with 47 W coil loss and 8.2 W iron-core loss at rated conditions; factor that heat into your cabinet ventilation.","metaTitle":"Siemens 4EP3702-2DS00 Commutating Choke, 22.5 A, 1.2 mH","metaDescription":"Siemens 4EP3702-2DS00 commutating choke for converters. 3-phase AC, 500 V, 22.5 A rated, 1.2 mH, IP00, screw terminals.
