What the ratings mean for fit
The AF95-30-11-70: The 150 A rating is the continuous current the main poles carry in AC-1 duty (resistive loads). For motor loads (AC-3), derate per ABB's standard curves — typically around 95 A for a 3-phase induction motor. The 100-250 V AC/DC coil covers most common control voltages across global panels; it pulls in reliably down to about 85 V and holds to about 18 V on DC drop-out. The 1 NO + 1 NC auxiliary contacts are wired for feedback or interlock without adding a side-mount block.
Where it lands in a panel
Snaps onto DIN rail or mounts with screws through the base slots. The 100-250 V coil means a single control transformer can feed both the contactor and the PLC output module — no separate 24 VDC supply needed for the coil. The auxiliary contacts share the same terminal numbering as the AF series, so a pre-wired panel layout carries over without re-routing.
