MCCB for line protection — 16 A, 4-pole, TM220 release
The 3VA1196-4EE46-0AA0: Breaking capacity is the headline number here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. At 240 V, that 121 kA rating puts it in the high-interrupting category for a 16 A frame — it can ride through a bolted fault on a large transformer secondary without rupturing. Thermal derating is flat from 40 °C through 55 °C — still 16 A — then drops to 15 A at 60 °C and holds there through 70 °C. That means in a warm panel (say 50 °C ambient), you get full ampacity; only above 55 °C do you lose 1 A.
Panel fit and physical integration
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard MCCB footprint for the 160 A frame class.
