It is designed to switch control circuits — pilot devices, PLC inputs, contactor coils — rather than motor loads directly. The 10 A rating at 230 V AC covers the vast majority of 24 VDC and 230 VAC control loads in a panel, so this part handles the signal-level switching that the main contactor does not.
The size S00 footprint — 45 mm wide, 70 mm high, 73 mm deep — fits the compact rail space typical of a motor control centre or distribution panel.
It has 2 normally-open instantaneous contacts. Rated 10 A at 24 V AC, 10 A at 230 V AC, 3 A at 400 V AC, and 0.26 A at 600 V AC. The mechanical life is typical 30 million operations.
Width 45 mm, height 70 mm, depth 73 mm. It mounts on a 35 mm DIN rail.
Both are size S00 auxiliary contactors with 2 NO contacts. The -2AV60 is a 24 V DC coil variant; the -2AP60 uses an AC coil. If your panel was wired for a DC coil, the -2AP60 will not drop in without a coil voltage change. The mechanical footprint and contact ratings are otherwise the same.
