The Siemens 3VA2110-5HL32-0CC0 is a SENTRON 3VA molded case circuit breaker (MCCB) for line protection, rated 100 A continuous current and packing 187 kA interrupting capacity at 240 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream. Three poles, ETU320 electronic trip unit, no ground-fault or phase-failure detection built in — this is a straight line-protection breaker, not a motor-protection or GFCI variant.
Interrupting ratings and thermal derating
At 415 V and 440 V it still holds 121 kA; at 500 V it drops to 79 kA; at 690 V it's 4.25 kA — that steep fall-off at 690 V means this breaker is sized for 400/480 V class systems, not 690 V main feeders. Above that it derates: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, 85 A at 70 °C. If your panel ambient runs 60 °C, you're limited to 92.5 A continuous — plan the load accordingly.
The storage floor matters if this sits in an unheated warehouse before commissioning.
