The ABB AF190-30-00-13 is a 3-pole non-reversing contactor rated at 156 A with a 100-250 VAC/DC coil. In a cement plant environment, that coil voltage range means it can be driven from the same control transformer feeding the PLC cabinet — no separate DC supply needed for the contactor logic. The 156 A rating handles the full-load current of a 75 kW mill motor or a preheater fan drive, but watch the AC-3 derating if you are switching squirrel-cage rotors directly; the AF190 frame carries the thermal capacity for repeated starts under load.
The 156 A rating is the general-purpose (AC-1) resistive load current. For motor duty (AC-3), the AF190 frame typically derates to around 110-115 A — enough for a 55 kW motor at 400 V. The 100-250 VAC/DC coil is a wide-range electronic coil that holds in without a separate economizer circuit; it drops out cleanly below about 85 V, which gives you a predictable undervoltage release point. In a dusty MCC room, the sealed coil design avoids the carbon-track failures that plague economized AC coils on contactors that cycle every few minutes on a clinker crusher.
Deployment Context
It accepts standard ABB AF-series auxiliary contact blocks and mechanical interlocks for reversing pairs. The 3-pole configuration handles three-phase loads; for a reversing starter you need two units with a mechanical interlock kit. The coil terminals accept ring or fork lugs up to 6 mm², and the main power terminals take cable up to 95 mm² — sized for the 156 A feed from the MCC bus.
