Rated 346 A continuous with a 384 A maximum at 60 Hz, it handles the full load current of a large AC drive or multi-drive section.
The 346 A rated current (I_LN) is the continuous thermal capacity at 40 °C ambient, Class H insulation (180 °C thermal class per IEC 60085). That rating assumes free-air convection in an IP00 open-frame enclosure — no forced cooling, no derating for enclosure heat rise. The 384 A maximum (I_thmax) at 60 Hz is the short-term overload ceiling; exceeding it risks saturating the core and losing inductance, which defeats the choke's purpose. The 480 V AC rated voltage matches standard 400 V class drives with a 10 % headroom for line swells. The 3.34 % voltage drop at rated conditions is the figure to match against the drive manufacturer's minimum line impedance requirement — if the drive calls for 3 % to 5 % impedance, this choke lands in the sweet spot. Power loss splits into 220 W in the coil (copper loss) and 114 W in the iron core (hysteresis and eddy-current loss), totaling 334 W at rated load. That heat must be vented from the enclosure — in a sealed cabinet, the temperature rise may exceed the 40 °C ambient rating unless forced-air cooling is added.
Where it goes — deployment context
This is an IP00 open-frame component — no enclosure, no finger-safe terminals. It mounts inside a panel or drive cabinet on a baseplate or mounting rail (dimensions 0.3 m wide × 0.269 m tall × 0.211 m deep). The flat-type terminals accept busbar or heavy-gauge cable lugs; plan for adequate clearance around the terminations per IEC 61439-1 for the 346 A circuit. The 0.64 mH inductance is a fixed value — not adjustable — so verify the drive's DC-link capacitance and switching frequency against the choke's resonant frequency to avoid harmonic amplification.
