The same pole set also carries an AC-1 rating for resistive and heating loads, so it'll handle lighting or heater banks without derating. One auxiliary normally-open contact is built in, enough for a seal-in or a status feedback to a PLC input.
This is a panel-mount contactor, DIN-rail or screw-fixed depending on the mounting accessory you pair it with. The AC coil circuit needs its own suppression (RC snubber) if you're switching it with a PLC output or a solid-state relay.
