It's a C-curve device rated for universal current — AC or DC — so it handles both line and DC loads in the same panel.
Two-pole design means it switches both line and neutral — but the evidence notes neutral conductor switching is not enabled, so treat it as a switched-line, solid-neutral device unless the wiring plan says otherwise. That covers most outdoor cabinets in northern climates and hot machinery sheds. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) means it won't rattle loose on a conveyor line or near a compressor.
