The interrupting rating varies with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. On a 480 V panel (common in North America) the 52.5 kA at 440 V is the closest published figure — expect it to be similar or slightly lower at 480 V. Width is 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). The breaker ships with a basic switch (order code 3VA11104EF360AA0) and provisions for up to 4 auxiliary switches (HQ type).","metaTitle":"Siemens 3VA1110-4EF36-0AE0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1110-4EF36-0AE0 molded case circuit breaker, 100A rated at 40°C, 3-pole, 121kA breaking capacity at 240V.

The difference is the trip unit: this one uses a TM240 thermal-magnetic release; the -5ED36-0AC0 variant uses a different trip curve.
