Rated insulation voltage Ui is 800 V, and the max operational voltage is 690 V AC 50/60 Hz or 600 V DC. That covers standard 400/480 VAC panels and many 600 VDC bus applications, but the DC rating is the limit to watch if you're switching a DC link. The short-time withstand is 2 kA at both 0.5 s and 1 s — this tells you the fault current the disconnect can handle momentarily while the upstream breaker clears. Mechanical endurance is 15,000 operations — that's the latching endurance, not the electrical life under load. For frequent switching applications, factor in derating for electrical wear at rated current. Power loss is 38 W maximum at rated current — relevant for thermal management inside a sealed enclosure. The main circuit connection is busbar-style via front terminals, so it's designed for a busbar distribution system in a panel — not for ring-tongue or box-lug wiring direct to cable. Plan for busbar drops and a front-access gland plate layout. The IP rating is only on the front face; the busbar connections at the rear are typically exposed inside the enclosure. That's standard for indoor industrial gear, but if the panel sits near a furnace or in a refrigerated area, the 70 °C upper operating limit is the binding constraint.","metaTitle":"Siemens 3VA1116-1AA42-0DA0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0DA0 switch disconnector, 160 A rated continuous current, 4-pole, IEC frame.
