Product details

No auxiliary contacts, no communication module, no trip indicator — this is a bare disconnect with a coil.

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.

Frequently asked questions

What is the closest functional alternative to 3VA1110-1AA32-0CA0?

The closest peer in the same SENTRON 3VA1 family is 3VA1112-5EF32-0CA0, but that is a full molded-case circuit breaker (line protection with TM240 overcurrent release) rated 125 A, not a switch disconnector. 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. They are not drop-in functional replacements — choose based on whether you need
