The 3VA1110-6EF36-0AB0 is a Siemens SENTRON molded case circuit breaker designed for line protection. The breaking capacity sits at 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you it handles high-fault scenarios like transformer secondaries or large motor branch circuits where available fault current is serious. The supplied basic switch is order code 3VA11106EF360AA0, which means the breaker ships with that internal mechanism pre-installed — you are not ordering a bare frame and a separate trip unit.
Thermal derating — the real-world current you get
At 55 °C it drops to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. The breaker's maximum power loss is 25 W, which factors into the thermal budget of a tightly packed panel.
Physical fit and mounting
The width of 76.2 mm (3 inches) is standard for a 3-pole frame in this class, so it drops into a panel cutout or busbar layout that was dimensioned around a typical 100 A MCCB without surprises.
