What the 104 A rating means for your panel
That 104 A figure is the conventional free-air rating under IEC 60947-4-1; for enclosed or high-ambient installations, derate per the thermal curve in the product manual. The 30-22-13 suffix indicates the auxiliary contact configuration — two normally open and two normally closed on the main block, plus one additional changeover — enough for basic interlocking and status feedback without an add-on side-mount.
Mounts on DIN rail via the integrated clip. The 104 A rating calls for a minimum 35 mm² copper cable on the power terminals; plan for a 2–3 cm bending radius between the contactor and the overload relay or busbar. The control coil voltage is not stated in the brief listing — verify the coil marking on the unit before wiring the control circuit.
