SENTRON 3VA1116-6EF36-0BA0 — 160 A MCCB with UVR, current production
The Siemens SENTRON 3VA1116-6EF36-0BA0 is a 3-pole molded case circuit breaker rated 160 A at 40 °C, designed for line protection in distribution panels. Breaking capacity hits 220 kA at 240 V — enough for high-fault utility feeds or transformer secondaries where SCCR headroom matters. An undervoltage release (UVR) is built in, so it drops the load on loss of control voltage without a separate shunt trip module. Rated insulation voltage is 800 V, and the thermal-magnetic trip unit is the TM240 type — fixed thermal, fixed magnetic, no adjustment. Power loss maxes at 40.5 W, which matters for enclosure heat rise if you're packing several breakers in a small panel.
Breaking capacity across voltage — selectivity planning
The 3VA1116-6EF36-0BA0 delivers 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That 17 kA floor at 690 V is the limiting figure for coordination studies — if your upstream transformer can push more fault current at that voltage, you need a current-limiting upstream device or a larger-frame breaker. Thermal derating starts at 55 °C: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, 150 A at 70 °C. Operating range is -25 °C to 70 °C ambient; storage from -40 °C to 80 °C. For a 160 A continuous load, keep ambient below 50 °C to avoid nuisance tripping.
Panel fit — dimensions and mounting
Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). Three-pole footprint matches the standard SENTRON 3VA mounting plate pattern — no adapter needed for existing 3VA panel layouts. No communication function, no ground-fault monitoring, no trip indicator on this variant.
