Breaking capacity hits 440 kA at 240 V and still delivers 330 kA at 415/440 V, so it's sized for high-fault infrastructure — main switchboard or large sub-distribution where the available fault current is substantial. Dimensions are 181 mm high, 140 mm wide, 86 mm deep — fits a standard MCCB cutout in a distribution panel; the 140 mm width is typical for a 4-pole frame at this rating. Communication function is built in, so you can integrate it with a higher-level monitoring system without an add-on module — check the ETU860 manual for protocol specifics.","metaTitle":"Siemens 3VA2116-8KQ42-0AA0 SENTRON MCCB, 160A, 4-Pole, ETU86","metaDescription":"Siemens SENTRON 3VA2116-8KQ42-0AA0 molded case circuit breaker, 160A rated current, 4-pole, ETU860 release, 440 kA at 240 V.
