The Siemens SENTRON 3VA2010-6HN36-0DC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, built around the ETU350 electronic trip unit for line protection. It carries a 242 kA interrupting rating at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V — so the high fault-current capability at the lower voltages is what makes this breaker a fit for high-capacity distribution panels where available fault current is substantial.
The 100 A rating holds flat from 40 °C through 50 °C, then derates to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. Plan your load margin accordingly if the breaker shares space with heat sources. If you need remote monitoring or phase-loss protection, that would be a different trip unit or an add-on module. Maximum power loss is 16 W — modest for a 100 A frame, so heat buildup in a dense panel is manageable. The UVR coil will drop the breaker if control voltage is lost, which is standard for emergency-stop or safety isolation circuits.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA2 frame.
What this breaker does not do
This is a straight line-protection MCCB — overcurrent and short-circuit only, with undervoltage release as the sole auxiliary function. If your application demands ground-fault or phase-loss protection, you would add an external relay or step up to a different 3VA variant with those features built in.
