Main circuit connects via busbar at front terminals — no wire lugs, so it's sized for a busbar drop in a panel. This is a pure disconnect — no overload protection, no short-circuit protection, no undervoltage release, no trip indicator. It's a load-break switch designed for isolation and manual switching, not circuit protection. Mechanical service life is 15 000 operating cycles typical — solid for a disconnect that sees once-per-shift or maintenance switching. The 2 HP auxiliary contacts (2 CO contacts) are built in, so you get status feedback without an add-on block. Front face is IP40 — fine for a closed panel; not for washdown zones. Optional motor drive available if you need remote operation. Maximum power loss is 38 W — account for that in the panel thermal budget if you're packing several disconnects in a small enclosure.","metaTitle":"SENTRON 3VA1110-1AA42-0AB0 Switch Disconnector, 100 A, 4-Pol","metaDescription":"SENTRON 3VA1110-1AA42-0AB0 4-pole switch disconnector in MCCB design.
