Breaking capacity — what the voltages tell you
The 3VA2163-5JQ46-0AA0: This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Thermal performance — no derating up to 70 °C
That is unusual for an MCCB — most frames start derating above 40 °C.
Adjustability and ground-fault monitoring
The breaker has an adjustable thermal-magnetic trip: the Initial Value is 16 A and the Full-Scale Value is 63 A, meaning the continuous current pickup can be set anywhere between those limits via the dial. It does not have a Trip Indicator or Undervoltage Release. The ground-fault monitoring version uses summation current formation on the L + N conductor — it monitors the vector sum of phase and neutral currents, so it catches leakage to ground without a separate sensor. A Communication Function is present, which means it can report status or trip events over a bus — useful for a monitored distribution panel.
Mounting dimensions and panel fit
If you are swapping into an existing panel that was built around that alternate MPN, the mounting hole pattern and bus connection points are the same.
