The Siemens SENTRON 3VA1010-3ED36-0JA0 is a 3-pole molded case circuit breaker rated 100 A at 40 °C, with a breaking capacity of 75.6 kA at 240 V — enough headroom for high-fault utility feeds or transformer secondaries where the available short-circuit current is substantial.
Integration notes
The 3VA1010-3ED36-0JA0 occupies 70 mm depth, 76.2 mm width, and 130 mm height — standard panel footprint for a 3-pole MCCB in this class. The shunt trip (STL) auxiliary release means you can wire an emergency-stop or undervoltage coil into the breaker without adding an external contactor.
Thermal derating
Rated 100 A continuous at 40 °C, and it holds that rating through 50 °C. Above 55 °C it derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C.
