It carries a 220 kA interrupting rating at 240 V — that's the figure that governs fault clearing on a 240 V secondary side; at 415 V it still holds 154 kA, and at 690 V it drops to 17 kA, so the SCCR headroom depends on your system voltage.
Panel footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB spacing on a DIN rail or direct-mount plate. The 12 W max power loss is low enough that derating for adjacent units in a sealed enclosure is minimal, but if you're packing six of these in a row at 70 °C ambient, the 19 A derate kicks in.
No trip indicator, so fault diagnostics rely on the auxiliary switch state or a separate indication module. The voltage trigger refers to the shunt trip coil — apply rated voltage and it opens the breaker remotely, useful for emergency-stop circuits or remote load shedding.
