The AF12-30-22-13: The 11 A rating under AC-3 duty (motor switching) governs the real-world load it can handle — sized for small motors, pumps, or fan starters up to roughly 3 kW at 400 V. The 3-pole configuration with two normally-open and two normally-closed auxiliary contacts (the 22-13 suffix) gives you feedback and interlocking without an add-on block — useful for reversing starters or star-delta timing circuits.
Where It Lives in the Panel
The compact AF12 frame leaves room alongside overload relays and terminal blocks for dense layouts.
