Product details

Mains Choke for Variable-Frequency Drives

The Siemens 4EU2452-4UA00-0AA0 is a three-phase mains choke (line reactor) designed for installation ahead of a frequency converter. It carries an 80 A maximum current rating and a 0.35 mH inductance, sized for 400/480 V AC supplies at 50 or 60 Hz.

Rated operational current is 72 A, with a thermal maximum of 80 A. Total power loss splits between the coil (123 W) and the iron core (37 W), so 160 W of heat must be dissipated into the enclosure; IP00 means no enclosure of its own, so panel airflow must handle that thermal load. Flat-type terminals accept busbar or cable lug connections — not spring-cage or screw-clamp. Verify the terminal aperture against your lug width before panel layout.

Panel Integration

Footprint is 0.225 m wide by 0.147 m deep by 0.21 m tall. Mounting clearances should follow Siemens standard practice for reactors: minimum 100 mm to adjacent components on all sides for natural convection cooling, given the 160 W dissipation.

Frequently asked questions

Where can I buy 4EU2452-4UA00-0AA0 and what is the lead time?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead-time and price quote.

What compliance documentation does this choke carry?

The choke is UL and CSA recognized under EN 61558-2-20, the safety standard for reactors and chokes. It also carries CE marking as a Siemens industrial product.

What is the voltage drop across this choke at rated current?

The relative inductive voltage drop is 4% at rated current, voltage, and frequency. This means at 72 A and 400 V, the choke drops about 16 V line-to-line.
