The ABB AF370-30-00-11 is a three-pole contactor rated 361 A, with a dual-voltage coil accepting 20-60 VDC or 24-60 VAC. This is the core switching element for motor loads, resistive heaters, and other high-current industrial circuits in a control panel. The 361 A rating in AC-3 duty (motor switching) means it handles induction motors up to roughly 200 kW at 400 V — the number that governs real-world sizing, not the higher AC-1 resistive rating.
Coil voltage range — what it means for panel integration
The 20-60 VDC / 24-60 VAC coil gives flexibility across control voltages common in industrial panels — 24 VDC, 48 VDC, or 24 VAC, 48 VAC, 110 VAC all fall within range. No separate coil rating needed per voltage. The wide DC range also covers battery-backed or UPS-fed control circuits where voltage may sag. Mounts on DIN rail or panel plate; the 361 A frame size typically requires a 4- or 5-pole footprint, so verify fill factor against existing gland plate layout.
