The 3RT2337-1AK60: Rated operational current hits 10 A at both 24 V and 230 V — that is the AC-1 resistive load curve. For motor duty (AC-3), the 690 V rating of 1 A tells you this contactor is sized for smaller motors; it is not a 7.5 kW class block. The 10 A at 230 V also covers resistive heater banks or lighting contactor applications on single-phase 230 V lines. Arcing time runs 10 to 20 ms, and the main contacts close in 10 to 18 ms — fast enough for most PLC-driven sequences.
Mounting and wiring — panel integration
That covers most DIN-rail layouts without special brackets. The contactor accepts 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded per terminal — standard panel wire sizes. Two auxiliary switch blocks can be attached on top (attachable auxiliary switches: 2).
