The Siemens 3VA1116-4FE46-0AA0 is a SENTRON molded case circuit breaker rated 80 A continuous, 4-pole, with a TM220 thermal-magnetic release — meaning the thermal element is fixed at 80 A and the magnetic pickup is 10× In (800 A) for short-circuit protection. Breaking capacity runs 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream.
At 55 °C it derates to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A.
Integration notes
The 4-pole design handles three-phase plus neutral, common for 400/415 V distribution.
