The interrupting capacity at 240 VAC is 121 kA, dropping to 75.6 kA at 415 VAC and 52.5 kA at 440 VAC — figures that govern its application on high-fault utility or transformer-secondaries. ## Interrupting Capacity and Application Context The 121 kA at 240 VAC places this MCCB in the high-interrupting category, suitable for main distribution panels fed by large transformers where available fault current exceeds 100 kA. At 415 VAC the 75.6 kA rating still covers most industrial service-entrance applications. No ground-fault monitoring or communication function is integrated — this is a straightforward line-protection device with shunt trip for remote or emergency tripping. ## Physical Integration and Mounting The shunt trip (STL) occupies one auxiliary slot; the two auxiliary switches and trip alarm switch (HQ) fill the remaining positions. Verify free-wheeling diode polarity on the shunt trip coil if energizing from a DC supply. ## Thermal Performance and Power Loss Maximum power loss is 25 W at rated current. The breaker maintains full 100 A rating from 40 °C through 50 °C; derating begins at 55 °C (98 A) and reaches 91 A at 70 °C.","metaTitle":"Siemens 3VA1110-4EF36-0JH0 SENTRON MCCB, 100 A, 121 kA at 24","metaDescription":"Siemens 3VA1110-4EF36-0JH0 SENTRON molded case circuit breaker, 3-pole, 100 A, 121 kA at 240 VAC.
