The 3VA frame is the workhorse of the SENTRON family — this variant is the full-current 160 A unit with the highest short-circuit ratings in the lineup.
The 3VA1116-4EE36-0AA0 delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel in North America, the 52.5 kA at 440 V is the closest published figure; for 400 V systems common in Europe, the 75.6 kA at 415 V provides generous headroom above typical available fault currents.
Thermal derating — don't oversize the bus
Above that, the TM220 release begins to thermally limit: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Plan the upstream conductor and bus accordingly.
The 76.2 mm width (3 inches) is standard for a 3-pole MCCB in this class — it occupies three 25 mm module positions on a DIN rail.
Key electrical ratings at a glance
Insulation voltage rated at 800 V, giving headroom for 690 V systems. The TM220 release provides thermal-magnetic protection with a fixed thermal curve and magnetic pickup, suitable for cable and busbar protection in distribution.
