The 3-pole construction and interrupting capacity of 187 kA at 240 VAC (121 kA at 415/440 VAC, 75.6 kA at 500 VAC, 3 kA at 690 VAC) mean it can clear high-fault currents on industrial feeders without upstream coordination issues.
Built-in undervoltage release and auxiliary switching
The auxiliary switch configuration includes two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ type), giving the control system status feedback on breaker position and fault events.
The 86 mm depth (3.39 in) leaves clearance for rear-access wiring in a typical distribution panel. Mounting is via the SENTRON base plate or DIN rail adapter; the 3-pole body fits the same cutout as other 3VA frame sizes.
