Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker is built for high-fault panels where a standard MCB would weld shut.
The 16 A rating holds flat from 40 °C to 50 °C, then derates to 15.36 A at 55 °C and 14.4 A at 70 °C.
Width 76.2 mm (3-pole), depth 70 mm, height 130 mm. The 3VA family uses a common mounting pattern, so swapping from another 3VA frame is straightforward — same DIN rail clip, same busbar pitch. The undervoltage release is present, so verify coil voltage matches your control circuit before wiring.
