The SIDAC 4EP4000-5MS00 is a 3-phase filter reactor rated for 400 V AC at 50 Hz, with a rated current of 18.5 A and a maximum of 20.5 A. It delivers 12.5 kvar of reactive power with a 7% relative throttling factor, making it a line-reactor choice for harmonic mitigation and inrush current limiting on motor drives or power-factor-correction banks. The 0.0031 H inductance and 189 Hz resonant frequency define its filtering band.
At 0.143 m deep, 0.219 m wide, and 0.179 m tall, it occupies a moderate footprint — verify clearance for the 87 W heat dissipation at full load, and ensure airflow around the Class B insulation system.
