Product details

It carries a rated current of 88.6 A and a maximum current of 98.4 A, with an inductance of 0.3 mH and a relative inductive voltage drop of 4%. The choke is designed per EN 61558-2-20 and uses flat-type terminals for the main circuit connection.

Rated current of 88.6 A is continuous at 50 °C ambient and thermal class F. Maximum current of 98.4 A at 60 Hz is the short-duration overload limit. The 4% voltage drop affects commutation notching. For DC-side applications, rated at 120.5 A DC.

This is an IP00 open-frame choke — no enclosure, no touch protection. It mounts inside a cabinet, typically on a mounting plate or chassis, not on a DIN rail. Dimensions are 0.219 m wide, 0.179 m tall, and 0.143 m deep. The flat-type terminals accept busbar or cable lugs; plan for adequate clearance around the choke for airflow, as total power loss (coil plus iron core) is 120 W.
