Its breaking capacity is specified across four voltage levels: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V — giving you the SCCR headroom to coordinate with downstream devices in most industrial low-voltage networks.
The 200 A rating holds flat from 40 °C through 50 °C ambient; above that it derates in 6 A steps per 5 °C increment, reaching 176 A at 70 °C — a curve to check if the breaker sits in a hot enclosure or next to other heat sources.
It is designed to accept a shunt trip (STL) auxiliary release, order code 3VA9688-0BL30, but does not ship with one installed. It comes with 2 auxiliary switches (HQ type) pre-installed.
