SENTRON 3VA1216-6EE32-0AA0 — 160 A MCCB with TM220 Release
The interrupting ratings span the common industrial voltages: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. At 415 V — a typical three-phase distribution voltage in many regions — the 154 kA SCCR gives substantial headroom for high-fault installations without cascading upstream breakers.
The breaker carries a full 160 A from 40°C through 50°C ambient, then derates to 156 A at 55°C, 151 A at 60°C, 147 A at 65°C, and 142 A at 70°C. In a sealed enclosure or high-ambient machine cabinet, that derating curve is the real selection limit — not the 40°C nameplate. The 105 mm width (4.13 in) and 158 mm height (6.22 in) fit standard SENTRON 3VA panel footprints; depth is 70 mm (2.76 in).
