Product details

What this choke does in your drive circuit

It limits current rise and harmonics on the input side of a variable-frequency drive or DC drive, protecting the rectifier diodes and reducing line notching. Rated at 56.7 A continuous with a 63 A maximum, with an inductance of 0.00045 H and a 4% relative inductive voltage drop at rated conditions. Thermal class B insulation per IEC 60085, rated for a 40 °C ambient. Total power loss at rated load is 104 W (71 W coil + 33 W iron core) — that heat has to be dissipated into the enclosure air; plan for ventilation or derating if the panel runs hot.

Mounting and connection reality

IP00 — no enclosure, no touch protection. Dimensions are 0.219 m wide × 0.179 m tall × 0.143 m deep, so it takes up about the footprint of a small contactor but with more depth. Main circuit connects via flat-type terminals — expect bus-bar or ring-tongue lugs, not spring-cage or screw-clamp.

Lifecycle status is listed as mature — meaning it is a stable, long-running design, not recently introduced and not flagged for discontinuation.

Frequently asked questions

Will 4EP4000-0DS00 drop into a panel specified around 5SJ3140-7?

No — those are completely different device classes. The 5SJ3140-7 is a single-pole miniature circuit breaker (MCB) rated 40 A at 240 V AC. The 4EP4000-0DS00 is a 3-phase commutating choke for converter input circuits. They are not form-fit-function interchangeable and serve different roles in the panel.
