The Siemens SENTRON 3VA2110-5HL32-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C up to 70 °C — no derating needed in a warm panel. At 500 V it still clears 75.6 kA; at 690 V the rating drops to 3.7 kA — that last figure tells you this breaker is sized for 400–480 V distribution, not 690 V motor circuits.
The adjustable thermal-magnetic trip range goes from 150 A minimum to 1 200 A maximum, so this breaker can be set to protect a feeder or a large motor branch within that window. The auxiliary switch block includes 2 form-C aux switches plus a separate trip alarm switch (HQ), letting the PLC see both the breaker position and whether it tripped on fault vs manual open.
Max power loss is 12.5 W at full load, so ventilation in a sealed enclosure is manageable but still worth checking against the panel's thermal budget.
