The Siemens SENTRON 3VA2110-6HL32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current rating of 100 A that holds across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting. The adjustable thermal-magnetic trip unit covers 150 A minimum to 1200 A maximum, so this breaker can be set to protect a feeder or a large motor branch without swapping the frame. Breaking capacity is 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is the one to watch if you are on a 690 V distribution system; that is a low-fault application only.
Integration details
Maximum power loss is 12.5 W — a modest figure that does not drive significant heat buildup in a ventilated enclosure, but worth including in your thermal calculation if the panel is sealed.
The adjustable trip range of 150–1200 A means this single frame covers a wide range of load currents; you set the trip coil to match the protected conductor, not the breaker frame.
