Product details

It carries a maximum continuous current of 28.1 A with a rated current of 25.3 A, and provides 2.56 mH inductance per phase. Thermal class B per IEC 60085 (130 °C winding temperature limit) with a 40 °C ambient rating; total power loss splits 77.6 W in the coil and 21.4 W in the iron core, so forced ventilation or adequate cabinet airflow is essential at full load.

Dimensions: 0.219 m wide, 0.179 m tall, 0.143 m deep — plan for that footprint plus clearance for the screw-type or tab terminals on the main current circuit. These are heavy-gauge terminals for the 25 A continuous rating; the 0.143 m depth is the body depth, not including terminal projection. Mounting is via the core's own foot or bracket — no DIN rail clip, so panel-mount hardware is required.
