Its 24 V AC coil pulls in at the rated voltage and holds through the standard AC dropout band. The main contacts are rated 9 A at 400 V for general use, and 4 kW in AC-3 duty at 400 V — that's the motor-switching number that governs real-world sizing for a 4 kW three-phase induction motor.
That covers most indoor panel environments without derating.
