What this MCCB delivers
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. The TM210 thermal-magnetic release gives fixed thermal and magnetic trip settings, so it's a straight swap for line-protection duty in distribution panels. No communication function, no ground-fault monitoring — this is a bare breaker with a shunt trip (STL) for remote opening.
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. Insulation voltage rated 800 V, so it's fine for 480 V and 600 V class systems with margin.
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. If your panel ambient runs hot, plan for the derated figure.
