Product details

Breaking capacity and current rating

The breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 76 kA at 440 V, and 30 kA at 500 V — these numbers govern the fault-clearing capability at the point of installation.

Rated current holds at 250 A from 40 °C up to 50 °C, then derates linearly: 243.3 A at 55 °C, 236.5 A at 60 °C, 229.8 A at 65 °C, and 223 A at 70 °C. Maximum power loss is 57 W. Front-side protection is IP40, meaning tools or fingers won't contact live parts during normal panel access.
