What it does not have — and this is the critical distinction for anyone sourcing it — is any overcurrent protection: no overload release, no short-circuit release. It is a load-break disconnect only, intended for isolation and switching duty where the upstream protective device handles the fault clearing. The 160 A rating holds flat from 40 °C to 50 °C, then derates to 158 A at 55 °C and 150 A at 70 °C. That means a panel ambient of 50 °C or below gets the full nameplate; above that, the continuous current drops by roughly 2 A per 5 °C step. Maximum power loss is 38 W — that is the heat it dumps into the enclosure, worth checking against your panel thermal budget if the disconnector runs near full load in a sealed cabinet. The shunt trip operates on a 220-250 V DC or 208-277 V AC control supply. That is a single-voltage-range coil — no undervoltage release, no leading contact. If your safety circuit requires a UVR or a delayed drop-out, this variant does not carry it; you would need a different order code in the 3VA1 family. ## Panel fit and connection The housing is 130 mm tall, 76.2 mm wide, and 70 mm deep — a compact 3-pole footprint that fits standard MCCB cutouts. The main circuit connects via busbar to front terminals, so the bus stabs come in from the front face, not the rear. That means the disconnector can be bus-tied in a distribution panel without rear-access wiring.","metaTitle":"Siemens 3VA1116-1AA32-0KH0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA32-0KH0 switch disconnector, 160 A at 40 °C, 3-pole, shunt trip, IP40 front.
