Its headline rating is 75 A at up to 415 V AC (AC-1 duty), which means it handles the steady-state current of resistive heaters, ovens, or lighting banks without the inrush stress of motor starting. The coil is 415 V AC 50 Hz wide-range, with a 160 VA inrush at 20 °C and a 6...10 W heat dissipation in the control circuit — a figure to budget for in a crowded panel.
Mounts on plate or DIN rail, with dimensions 85 mm wide × 127 mm high × 110 mm deep — a compact footprint for a 75 A 4-pole block. Power-circuit screw terminals accept 2.5...25 mm² flexible with cable end (solid up to 25 mm²); control-circuit terminals take 1...4 mm². Tightening torque is 5 N.m on the power side, 1.2 N.m on the control side.
