The Siemens 3VA2010-5HL36-0KA0 is a 3-pole molded case circuit breaker from the SENTRON 3VA series, rated for line protection at 100 A continuous current (Iu) with an ETU320 electronic trip unit. It delivers 187 kA breaking capacity at 240 V AC — that figure drops to 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V, so the voltage class of your distribution determines whether this breaker clears a fault without cascading upstream.
Above that, it steps down: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The shunt trip (STL) release (order code 3VA9688-0BL33) is built in, so you can remotely trip the breaker from an emergency-stop circuit or a PLC output without adding external undervoltage gear. No auxiliary contacts are included — those are ordered separately if you need status feedback.
