The 3RT2337-1AF00: That single auxiliary gives you one feedback or interlock signal without adding a side-mount block.
That covers the common motor-circuit wire sizes up to 14 AWG, and the dual-entry lets you loop through or parallel feeds without a separate terminal block.
It comes with one instantaneous auxiliary contact, rated for switching currents from 10 A at 24 V AC down to 0.1 A at 600 V AC. The contact block is integrated — no separate add-on required for a single feedback or interlock signal.
