The Siemens SENTRON 3VA2010-6HL32-0AF0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Its interrupting capacity is specified per voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. The 3 kA at 690 V is a derated condition for higher-voltage industrial systems; verify your system's available fault current against the voltage-specific rating.
Trip range and protection profile
The breaker's adjustable thermal-magnetic trip unit covers a continuous current range from 150 A to 1 200 A, though the frame itself is rated for 100 A continuous. That means the trip unit is sized for a larger frame than the continuous rating suggests — the 100 A continuous rating is the limit for sustained load, while the trip range allows coordination with downstream devices. The design is for line protection, not feeder or motor protection; it's intended for main or branch circuit protection where selectivity with downstream breakers matters.
