Product details

The 86 mm depth and 140 mm width fit standard backplate mounting — horizontal or vertical — with front-connect busbars or cable lugs.

Breaking capacity and trip curve

Breaking capacity ramps from 85 kA Icu at 240 V down to 8 kA at 690 V — the F-code rating (36 kA at 415 V) is the practical benchmark for most 400 V-class installations. The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection; the 250 A rating at 50 °C means no derating at typical panel ambient, though altitude derating applies above 2000 m.

Integration notes

Neutral is on the left (4D configuration with 1 x Ir neutral protection). The toggle handle provides local manual control; no rotary handle or motor operator is included. IK07 impact rating and IP40 enclosure protection suit panel-mount indoor use.
