Coil voltage and control-circuit fit
The AF185-30-11-70 carries a 100-250 V AC/DC coil, which means it operates directly from a standard control transformer or a DC supply within that band without needing an interposing relay or a separate coil-voltage converter. This wide-range coil is characteristic of ABB's AF series — it eliminates the need to specify a separate coil code for 110 V vs 230 V control circuits, simplifying BOM management across panels with different control voltages.
Type designation and switching duty
The Non-Reversing type means this contactor controls a load in one direction only — it has a single set of power poles and no mechanical interlock for forward-reverse switching. For a motor load that does not require reversing, this is the standard configuration; a reversing application would need two mechanically interlocked contactors or a dedicated reversing contactor assembly.
