Its interrupting capacity reaches 242 kA at 240 V and 187 kA at 415/440 V, dropping to 121 kA at 500 V and 7.5 kA at 690 V — so it handles high-fault utility feeds at low voltage but you need to check the available fault current at your service voltage before committing the BOM line. The shunt trip is wired separately from the main power path — verify coil voltage compatibility with your control voltage before wiring.
Mounting and footprint
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size for 400 A.
