It is a 3-pole device with no overload or short-circuit protection built in; its job is safe isolation under load, not fault interruption. The integrated undervoltage release (UVR) at 24 V DC drops the contacts if control power is lost, which is standard for emergency-stop or safety-related disconnecting means in a panel. It carries two auxiliary switches (HQ type) plus a separate trip alarm switch — three CO contacts total — so you get status feedback for both the main contact position and any UVR-triggered trip event. The auxiliary switch design is integrated into the front terminal arrangement, which uses busbar connection on the main circuit. The 3VA1110-1AA32-0BH0 mounts in the standard 3VA1 IEC frame 160 footprint: 70 mm deep, 76.2 mm wide, 130 mm tall. The UVR coil holds at 24 V DC; verify your control transformer sizing if you're feeding multiple releases from the same supply.","metaTitle":"Siemens 3VA1110-1AA32-0BH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0BH0 SENTRON switch disconnector, 100 A continuous, 3-pole, undervoltage release 24 V DC.
