It sits between a variable-frequency drive and the motor to limit the rate of voltage rise (dV/dt) from the drive's PWM output, protecting motor winding insulation on long cable runs. The 0.00028 H inductance and 10.9 % impedance (UK) are sized to smooth the drive's switching edges. ## Mounting and integration into a panel The 4EP4300-0EK00 measures 0.26 m wide by 0.22 m tall by 0.12 m deep and uses screw-type terminals for the main circuit connections. At IP00, it has no enclosure protection — it is an open-frame component meant for installation inside a grounded metal panel or cabinet. The thermal class B insulation (130 °C continuous) and ambient temperature rating of 40 °C mean it sheds about 127.6 W total losses (73.2 W coil + 54.4 W iron core) into the enclosure; that heat must be factored into the panel's ventilation or cooling design. Mount it on a flat backplate or chassis, not on a DIN rail — there is no rail clip.","metaTitle":"Siemens SIDAC 4EP4300-0EK00 output reactor, 43A, 6400Hz","metaDescription":"Siemens SIDAC 4EP4300-0EK00 3-phase output reactor, 43A max, 6400Hz rated frequency, IP00, screw terminals.
