The ABB AF205R-30-22-13 is a reversing contactor, 3-pole, used to switch the direction of a three-phase motor by interchanging two phases. The reversing contactor class is deployed in motor control centers and panel builds where a motor must run forward and reverse — conveyors, hoists, and positioning drives are typical loads. The 3-pole construction handles all three phases, and the reversing interlock (mechanical or electrical) prevents both contactors from closing simultaneously.
The description confirms this is a reversing contactor with 3 poles — the 'R' in the order code signals the reversing variant. The 3-pole construction handles all three phases.
