The Siemens SENTRON 3VA2010-7HN36-0AA0 is a 3-pole molded case circuit breaker rated for a continuous current of 100 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its ETU350 electronic overcurrent release handles line protection with adjustable trip curves, and the interrupting capacity hits 330 kA at 240 V, 242 kA at 415/440 V, and 187 kA at 500 V, dropping to 3 kA at 690 V.
Panel fit and environment
The power loss is 7.7 W maximum, so thermal rise inside a sealed cabinet is manageable with basic ventilation.
