Product details

For resistive loads (AC-1) at 230 V and 60 °C, it carries 23 kW. Main circuit connections use screw-type terminals accepting 2x (0.75... 25 mm²) stranded or 2x (0.5... 4 mm²) solid, with a minimum 16 mm² conductor at 60 °C. The auxiliary and control circuit also uses screw terminals. Side-by-side mounting is permitted, which saves rail space in dense panels.

The 73 mm width and 112 mm height fit standard S2 footprint; depth is 130 mm including terminals. For short-circuit coordination, the required fuse is gL/gG 63 A for type of assignment 2.
