The shunt trip (STL) release accepts 220–250 V DC or 208–277 V AC, and the auxiliary contact block carries 2 HQ auxiliary switches plus 1 trip alarm switch HQ. Front-terminal busbar connection, IP40 on the front face. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth — the 101.6 mm width is a standard 4-pole MCCB footprint, so it drops into existing 4-pole cutouts without rework. Front terminal busbar connection keeps wiring in the same plane as adjacent breakers.","metaTitle":"Siemens 3VA1110-1AA42-0KH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA42-0KH0 SENTRON switch disconnector, 100 A rated continuous current, 4-pole, shunt trip release, IP40 front.
