The interrupting capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V.
Key features and deployment context
The shunt trip allows remote tripping from a PLC or emergency-stop circuit — useful for motor control centers where you need to kill power from a safety relay without pulling the handle. The 4 W maximum power loss is modest for a 63 A MCCB, meaning less heat to manage inside a sealed enclosure. The trip indicator and voltage trigger are present; undervoltage release and ground-fault monitoring are not included on this variant.
