The Siemens SENTRON 3VA2110-5HL32-0BA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across its full ambient range from -25 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still clears 75.6 kA at 500 V — high enough for most industrial secondary-distribution panels where fault currents run hot.
Thermal performance and power loss
Maximum power dissipation is 12.5 W at rated load — modest enough that multiple breakers can be ganged in a panel without forced cooling, though you'll still want to follow the manufacturer's spacing guidelines.
