Breaking capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — figures that give the panel designer substantial SCCR headroom for high-fault installations. The frame measures 138 mm wide × 248 mm high × 110 mm deep, fitting the standard SENTRON 3VA mounting footprint. Panel builders should note the 37.5 W maximum power loss when sizing enclosure ventilation.
Trip unit and auxiliary configuration
The ETU350M overcurrent release supports motor protection with adjustable settings. The breaker includes a voltage trigger and a trip indicator for fault status at a glance.
Derating begins at 55 °C (240 A), stepping down to 225 A at 70 °C.
