That AC-3 rating means it's sized for motor switching under load, not just resistive heating.
AC-3 is the standard duty for squirrel-cage motors — making and breaking running current. The 48 V DC coil is common in control circuits fed from a 48 VDC supply (telecom or battery-backed panels). IP20 finger-safe per VDE 0106 means it's fine inside an enclosed panel but not for exposed mounting.
The preassembled reversing busbar saves panel space and wiring time — no external mechanical interlock needed. Mounts on a DIN rail. The 57 mm depth and 90 mm width fit a standard TeSys K footprint, so it swaps into existing layouts without re-drilling the backplate.
