It handles 690 V AC or 500 V DC operating voltage, making it suitable for motor feeder isolation, panel main switches, and load-break applications where overload or short-circuit protection is handled upstream or downstream. Built into the IEC frame 160 footprint, it measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact 3-pole block that fits standard panel layouts with front-terminal busbar connections for the main circuit. ## Integrated auxiliary and release options This variant ships with an undervoltage release (UVR) rated 208-230 V AC 50/60 Hz, plus 2 HQ auxiliary switches and 1 HQ trip alarm switch — providing three CO contacts total for status feedback to a PLC or indication panel.","metaTitle":"Siemens 3VA1110-1AA32-0DH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0DH0 SENTRON switch disconnector, 100 A rated at 40-70 °C, 3-pole, 690 V AC, with UVR and auxiliary switches.
