It is rated for 30 kW at 500 V and 22 kW at AC-2 duty at 400 V, which covers the bulk of standard induction motor applications in that power band. The 115 mm depth leaves clearance for wiring and auxiliary blocks.
The AC-3 rating (not explicitly listed here but implied by the S2 frame class) would cover standard squirrel-cage motors, where switching occurs at starting current only. Wiring terminals accept solid conductors up to 4 mm² per clamp (2x 0.75...4 mm² max) and stranded up to 25 mm² (2x 0.75...25 mm²), which covers the power feed for a 22 kW motor on a 4–6 mm² cable. The screw-type main terminals are straightforward for panel builders — no special tooling needed. The IP20 front protection means the terminals are finger-safe once wired, but the body itself is IP00 (open), so it must live inside an enclosure.
For a BOM line that was specified around the 3RT1036-1AB00 (the DC-coil variant), this 1AN60 (AC-coil, 50/60 Hz) will not drop in without a coil voltage change — the mechanical footprint and terminal layout are identical, but the coil driver circuit must match. If your panel was built for 24 VDC coil control, the 1AN60 won't work without rewiring the coil supply.
Side-by-side mounting is permitted, which saves panel width when ganging multiple contactors for a star-delta or reversing starter.
