Rated insulation voltage (Ui) is 800 V; max operational voltage hits 690 V AC 50/60 Hz and 500 V DC. That covers standard 400/480 VAC distribution and most 500 VDC bus applications, but watch the DC rating — it's the lower ceiling. Short-time withstand at 1 s and 0.5 s is 2 kA — this is a switch disconnector, not a breaker, so it's rated to carry fault current for the time it takes an upstream protective device to clear, not to interrupt it. The 38 W max power loss at rated current means the enclosure needs some ventilation if you're packing multiple units in a small panel. IP40 on the front keeps out tools and fingers but not water — mount it in a cabinet, not in a washdown zone. ## Panel fit and mechanical endurance Footprint is 76.2 mm wide, 130 mm high, 70 mm deep — standard 3-pole MCCB-style cutout for the 160 A frame. Busbar connection on the front terminals means it's designed for a distribution panel bus stack, not lugged cable tails. Mechanical endurance is 15 000 latching cycles — this is a switch disconnector, not a contactor; it's meant for infrequent isolation, not daily switching under load.","metaTitle":"Siemens 3VA1110-1AA32-0CA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA32-0CA0 switch disconnector, 100 A rated continuous current, 3-pole, with undervoltage release 120-127 V AC.

It shares the same 76.2 mm width, 130 mm height, 70 mm depth footprint and 3-pole front-terminal layout, so it will physically fit the same panel cutout. The deciding factor: the 3VA1110-1AA32-0CA0 is a bare isolator with UVR; the 3VA1112-5EF32-0CA0 is a breaker with adjustable thermal-magnetic trip and no UVR.
