What this MCCB carries and where it fits
The Siemens 3VA2010-5HL32-0JL0 is a SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C, with a 3-pole configuration and an ETU320 electronic trip unit for line protection. Its interrupting capacity hits 187 kA at 240 V and 121 kA at both 415 V and 440 V, dropping to 79 kA at 500 V and 3.4 kA at 690 V — so it handles high-fault service-entrance or distribution panels where the available fault current is substantial at lower voltages. The 800 V rated insulation voltage (Ui) means it's rated for 480/600 V class systems without derating the insulation. This breaker includes a shunt trip (STL) auxiliary release and an auxiliary contact block with 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ version). That's a full complement for remote tripping and status feedback — useful in a motor control center or a generator paralleling panel where you need to signal a trip condition back to a PLC.
Thermal derating and panel integration
At 40 °C, 45 °C, and 50 °C the breaker holds its full 100 A rating. At 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A. If your panel ambient runs above 50 °C, you need to account for that 1.5 A per degree drop above 50 °C. The maximum operating temperature is 70 °C; storage range is -40 °C to 80 °C. Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most SENTRON panelboards and distribution boards. The 13.5 W maximum power loss means you don't need forced ventilation in a typical enclosure, but it's worth checking the thermal rise if you're packing multiple breakers in a small can.
