MCCB for line protection with high interrupting capacity
Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — figures that place it well above typical panelboard SCCR requirements, so you can coordinate it upstream of downstream breakers without worrying about cascading failure during a bolted fault.
The breaker holds its full 16 A rating up to 50 °C ambient; above that it derates linearly to 14.4 A at 70 °C. If the panel runs hot — say, adjacent to a drive cabinet — use the 55 °C figure of 15.36 A for your continuous-load calculation. The 76.2 mm width and 70 mm depth fit a standard 3-pole MCCB footprint on DIN rail or a SENTRON mounting plate; the IP40 front face keeps dust out of the enclosure.
Auxiliary trip and release configuration
The integrated auxiliary trip is specified as order code 3VA9688-0BL32 — that is the shunt-trip module wired to the breaker's internal mechanism. No undervoltage release is fitted, so remote tripping relies on the shunt trip alone.
