The Siemens SENTRON 3VA2010-6HL32-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a rated continuous current Iu of 100 A and a rated insulation voltage Ui of 800 V. The 242 kA interrupting capacity at 240 V and 187 kA at 415 V mean this breaker handles high-fault-current scenarios typical in industrial main feeders or large motor control centers — it safely clears a bolted fault without upstream devices needing to trip, which is the core of selective coordination.
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that drops into existing Siemens switchboard or panel cutouts. No auxiliary contacts are fitted, and there is no communication module, so this is a standalone line-protection device. The shunt trip (STL) design of the auxiliary release allows remote tripping via a separate control voltage, useful for emergency-stop circuits or interlocking with a downstream contactor. The integrated auxiliary trip is order code 3VA9688-0BL30.
The breaker carries 100 A continuously up to 50 °C ambient. Above that, derating applies: 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 maximum operating temperature is 70 °C; storage range is -40 °C to 80 °C. In a hot panel — say a motor control center near a dryer section — the 85 A ceiling at 70 °C is the real limit, not the 100 A nameplate.
