Breaking capacity hits 121 kA at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — still substantial for downstream fault isolation in distribution panels. ## Breaking capacity and thermal performance This MCCB maintains its full 16 A rating across the 40 °C to 55 °C band — no early derating. Above that, it drops to 15 A at 60 °C through 70 °C. At 690 V the breaking capacity holds at 11.9 kA, same as at 500 V, which is unusual for this class — most breakers see a steeper drop above 500 V. ## Panel fit and auxiliary options Mounts on DIN rail or panel — 76.2 mm wide (3 in), 130 mm tall, 70 mm deep. Ships with a factory-installed shunt trip (STL) and two auxiliary switches plus a trip alarm switch (HQ configuration).","metaTitle":"Siemens 3VA1196-4EF32-0JH0 SENTRON MCCB, 16 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1196-4EF32-0JH0 molded case circuit breaker, 16 A rated, 3-pole, 121 kA breaking at 240 V.
