It is designed as a pure disconnecting means — no overload or short-circuit protection built in, so it functions as a load-break switch rather than a circuit breaker. The 690 V AC rating covers most 400/480 V industrial systems with headroom; the 500 V DC rating allows use in DC bus or battery circuits within that limit. The 3-pole configuration suits three-phase AC lines. The switch disconnector measures 70 mm deep, 76.2 mm wide, and 130 mm high — a compact footprint that fits standard 3-pole MCCB panel cutouts. The main circuit connection uses busbar connection via front terminals, meaning it accepts flat busbars or fork-type lugs on the front face. The auxiliary contacts (2 CO + 1 trip alarm) are wired separately for status indication.","metaTitle":"Siemens SENTRON 3VA1112-1AA32-0BH0 Switch Disconnector, 125","metaDescription":"Siemens SENTRON 3VA1112-1AA32-0BH0 switch disconnector, 125 A rated continuous current, 3-pole, 690 V AC / 500 V DC.
