Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and still holds 17 kA at 690 V, so it handles high-fault industrial feeds without cascading upstream.
Use the trip alarm to light a panel beacon or trigger a PLC fault routine. The shunt trip (STL) release is built in, not an add-on; wire it to a 24 VDC or 230 VAC source (check coil rating on the nameplate) for remote opening.
The breaker measures 138 mm wide, 248 mm high, 110 mm deep — a standard 3-pole MCCB footprint for 630 A frame. The ETU350 release is adjustable (long-time, short-time, instantaneous, ground-fault if equipped — here it's line protection only, no ground-fault module). The shunt trip release is factory-installed; verify the coil voltage matches your control voltage before wiring.
