630 A MCCB with 187 kA interrupting capacity
Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, and 75.6 kA at 500 V — figures that place it in the high-breaking class for fault-current duty on the line side of a facility's main switchboard. Two HQ auxiliary switches report breaker status back to the PLC or panel indication.
In a sealed enclosure or high-ambient panel, the 164.5 W maximum power loss must be vented — plan for forced airflow or a larger enclosure if the breaker is grouped with other heat sources.
