Unlike a molded-case circuit breaker, this unit provides no overload or short-circuit protection; it is a manual disconnect and isolation device. That distinction matters when filling a BOM: if the line calls for a load-break switch with visible isolation gap, this fits. If the spec requires overcurrent protection, you need a different 3VA variant with a thermal-magnetic release. ## Footprint and panel integration Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — the same 3VA frame-160 footprint shared by the line-protection MCCB variants. That means it drops into the same panel cutout and bus-bar arrangement as a 3VA1112-5EF32-0CA0 or 3VA1110-5ED36-0AC0 without rewiring, provided the bus bars and lug terminals match. Front-face IP40 protection suits enclosed panel mounting; no washdown rating.","metaTitle":"Siemens 3VA1110-1AA36-0CH0 Switch Disconnector, 100 A, 690 V","metaDescription":"Siemens SENTRON 3VA1110-1AA36-0CH0 switch disconnector, 100 A rated, 690 V AC, 3-pole, with undervoltage release 120-127 V AC, 2 aux + 1 alarm switch.
