The breaking capacity is what makes this part stand out for high-fault panels: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. This is the line protection version (not motor protection), so it's sized for feeder circuits, busbars, or distribution panels where you need to protect cable and bus against overload and short circuit. ## Panel integration and physical fit That 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole spacings — so it fits the usual DIN-rail or panel-mount cutout without surprises.","metaTitle":"Siemens 3VA1116-5EF32-0BA0 SENTRON MCCB, 160 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1116-5EF32-0BA0 molded case circuit breaker.
