The Siemens SENTRON 3VA2010-6HL32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its 242 kA breaking capacity at 240 V AC means it can safely interrupt very high fault currents without upstream damage — critical for installations where the available fault current is high and you need selectivity downstream.
Breaking Capacity Across Voltages
This MCCB delivers 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 steep drop at 690 V tells you this breaker is optimized for 240–500 V systems — at 690 V the interrupting rating is much lower, so verify the available fault current at that voltage before specifying.
Thermal Performance and Derating
The continuous current rating holds at 100 A from 40 °C all the way to 70 °C — no derating needed across the full operating temperature range. That simplifies panel layout when the breaker sits near other heat sources. The rated insulation voltage is 800 V.
Shunt Trip Release and Dimensions
Fitted with a shunt trip (STL) auxiliary release for remote tripping — useful in emergency-stop circuits or when a PLC needs to drop the breaker. The 105 mm width, 181 mm height, and 86 mm depth fit standard panel layouts; 13.5 W maximum power loss is manageable but should be factored into enclosure thermal calculations.
