What this MCCB does on the line
Breaking capacity climbs to 75.6 kA at 240 V, drops to 52.5 kA at 415 V, and still holds 10.5 kA at 690 V — that high-fault rating at the lower voltages means it can sit upstream of a sub-panel without worrying about series ratings or cascading failure. If your BOM calls for an undervoltage coil or a set of aux contacts, you'll need to add them separately.
Above that it steps down: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C. If your panel runs hot from tightly packed drives or a transformer nearby, size the load or the breaker for the actual ambient, not the nameplate 16 A.
