Product details

Rated for 500 V AC at 50 Hz, this choke is sized for 400 V class drives (typical line-to-line 400 V, with 500 V being the insulation/peak voltage rating). The 112.5 A rated current and 125 A maximum mean it can handle a 110 kW drive at 400 V (approx 200 A line current) is too large — this choke fits drives in the 55–75 kW range depending on load profile. The 4% voltage drop is the industry-standard impedance for DC bus reactors and input line reactors, balancing harmonic mitigation against voltage sag.

Mechanical and thermal considerations

IP00 protection means it is an open-frame component — no enclosure, no touch protection. The thermal class H insulation per IEC 60085 allows a 180 °C hot-spot temperature, which is standard for high-temperature reactor windings. Total power loss is 199 W (131 W coil + 68 W iron core at rated conditions), so forced air circulation or derating is required if ambient exceeds 40 °C. Connection is via flat-type terminals — expect bus-bar or cable-lug terminations, not screw clamps.

Frequently asked questions

What is the closest functional second-source for 4EU2522-5AA00-0AA0?

The peers listed (5SJ3140-7, 5SL3232-6MB, 5SJ6325-7RC) are miniature circuit breakers — a completely different component class. They are not functional substitutes for a commutating choke. No direct second-source exists in this evidence; the part is a specialized reactor.
