Breaking capacity hits 440 kA at 240 V AC and 330 kA at 415 V AC, meaning it can safely interrupt very high fault currents without upstream cascading — a key spec for high-SCCR industrial panels where the available fault current exceeds 200 kA. The 3-pole design and IP40 front protection suit standard switchboard or enclosed distribution use.
Integration notes
The ETU550 supports communication (via the integrated communication function), enabling remote monitoring and trip-event logging over the plant network.
