It also handles DC circuits up to 500 V. This is not a circuit breaker: it provides no overload or short-circuit protection. It's a manual disconnect switch for isolating a load under no-fault conditions. Built into the SENTRON 3VA platform, it shares the same 70 mm depth, 76.2 mm width, and 130 mm height as the frame-160 MCCB siblings. The IP40 front protection keeps dust and small tools out of the live parts in a clean panel environment. ## The undervoltage release — what it means on the line That's a standard safety function for motor branch circuits or conveyor lines: if the control power fails, the disconnect opens and the load stops. No leading contact on this UVR version, so it doesn't sequence a downstream contactor. The UVR is factory-installed and wired to the front terminals. There are no auxiliary contacts on this variant (0 CO contacts), and no communication module. If you need remote status feedback or a shunt trip, you're looking at a different 3VA order code. ## Where it fits — panel and load considerations At 76.2 mm wide (roughly 4.5 standard modular units), this switch disconnector takes up the same DIN-rail footprint as a 3-pole 3VA MCCB. Front terminals accept busbar connection — typical for a main disconnect or branch isolator in a distribution panel. The mechanical endurance is 15,000 latching cycles — that's a solid service life for a disconnect that sees a few operations per shift.","metaTitle":"Siemens SENTRON 3VA1110-1AA32-0DA0 Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0DA0 switch disconnector, IEC frame 160, 3-pole, 100 A, no overload or short-circuit protection, undervoltage release 208-230 V AC, IP40 front.
