The Siemens 3VA1116-1AA36-0CA0 is a SENTRON 3VA1 switch disconnector in MCCB design, rated for 160 A continuous current (Iu) across a 3-pole configuration. It carries a rated insulation voltage of 800 V and a max AC operational voltage of 690 V (50/60 Hz), with a DC rating of 500 V. This unit ships without overload or short-circuit protection — it is a pure disconnecting means, not a circuit breaker — and includes an undervoltage release (UVR) coil rated 120–127 V AC.
What the 160 A rating means for your panel
At 160 A continuous, this switch disconnector handles the full load current of a moderately sized feeder or a large motor branch circuit. The 3-pole front-terminal connection (clamp type) accepts standard lug wiring — expect to land conductors sized for 160 A (typically 2/0 AWG copper at 75 °C termination). The IP40 front protection means the operator face is sealed against tools and small debris, but the enclosure itself must provide the overall panel IP rating. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact footprint that fits standard DIN-rail or panel-mount cutouts for the 3VA frame 160 family.
