The interrupting capacity hits 121 kA at 240 V AC — that's serious fault-clearing for high-available-fault panels, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V. It carries a TM240 thermal-magnetic overcurrent release — fixed thermal curve, magnetic trip factory-set. This is a straight-ahead line-protection MCCB for standard feeder or branch circuits where you don't need the electronics package. A shunt trip (STL) release is integrated — part number 3VA9688-0BL30 for the release assembly itself.
Thermal derating — where the 16 A holds and where it doesn't
At 55 °C it derates to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A.
IP40 on the front, so it's fine for general-purpose indoor panels; not rated for washdown.
