Rated insulation voltage 800 V, operating voltage 690 V AC or 500 V DC. ## Built-in undervoltage release and auxiliary switches The UVR drops the disconnect on loss or dip of control voltage — standard for safety disconnects on motor feeders or conveyor lines where you want automatic opening on power loss. That's the heat to account for in a dense panel — not high for a 100 A device, but real if you're stacking several in a row. Main circuit connections are busbar-style via front terminals — the busbar stabs into the front face, not the rear. That means panel layout needs the busbar system planned ahead; it's not a random screw-clamp on the side. Dimensions: 76.2 mm wide (roughly 4.5 module-widths on a 17.5 mm DIN grid), 130 mm tall, 70 mm deep. Mechanical service life 15,000 operating cycles typical.","metaTitle":"Siemens 3VA1110-1AA32-0DC0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0DC0 SENTRON switch disconnector, 100 A rated current, 3-pole, MCCB design, with undervoltage release and 2 auxiliary switches.
