The ABB AF190-30-11-13 is a 275 Amp IEC contactor in the AF-Line series, built on the AF140 frame. It's a 3-pole unit rated for 600 V and carries a universal 100-250 VAC/VDC coil — meaning the same coil handles both AC and DC control voltages without needing a separate rectifier or coil changeout. That's handy when you're retrofitting an old panel with mixed control supplies or standardizing spares across lines that run different control voltages.
The 275 A rating is the general-purpose (AC-1) resistive load current. For motor duty (AC-3), the contactor derates — the actual switching current depends on the motor full-load amps and category, but the 275 A AC-1 figure tells you this contactor handles heavy resistive loads like heaters or large lighting banks at full rated current. The 100-250 VAC/VDC control coil eliminates the guesswork on control voltage. Whether your panel runs 120 VAC, 208 VAC, 240 VAC, or 110 VDC, this one coil covers it. That's a real advantage for MRO spares — one part number replaces several voltage-specific coils on the shelf.
This contactor is built for motor control centers, distribution panels, and heavy industrial machinery where you're switching motor loads, resistive heaters, or capacitor banks in the 200-275 A range. The AF-Line series is ABB's modular IEC contactor family — the AF140 frame shares mounting and accessory patterns with smaller and larger frame sizes in the same line, so adding aux contacts, interlocks, or mechanical linkages follows a consistent pattern across the panel.
