The interrupting capacity hits 121 kA at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — numbers that matter for high-fault panels where selectivity and SCCR headroom are the deciding factor.
The 16 A rating holds flat from 40 °C to 55 °C; at 60 °C it derates to 15 A, and at 70 °C it's still 15 A. That's a tight thermal curve — good for warm enclosures where you need the breaker to hold without nuisance trips. The TM240 release means the magnetic trip is fixed at 240 A (15× the thermal rating), so it's sized for motor inrush or transformer magnetizing currents that briefly spike above the thermal pickup. Interrupting capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V and 690 V.
The 3VA1196-4EF32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 3-pole MCCB with this fault rating.
