The Siemens SENTRON 3VM1116-3ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 160 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release.
Thermal derating and the real-world current limit
Above that it begins to step down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C (–). The maximum power loss of 38 W is the heat the breaker dumps into the enclosure; factor it into the thermal budget.
The 4-pole footprint matches a standard MCCB cutout for a 160 A frame.
