The Omron J7KNA-09-01 24VS is a contactor from the J7KNA series (Motor contactors from 4-5.5kW for normal duty switching). Omron describes it as: Contactor, 3-pole, 9 A/4 kW AC3 (20 A AC1) + 1B auxiliary with diode suppressor, 24 VDC.
A contactor is the switching element of a motor starter: the control circuit energises the coil and the main contacts connect the motor to the supply. Contactors wear with every start, so they are frequent maintenance parts.
