The Siemens 3VA1116-1AA32-0BC0 is a SENTRON switch disconnector in an MCCB-style frame — 3-pole, rated for 160 A continuous current (Iu), with a maximum AC operating voltage of 690 V and DC of 500 V. It has no overload or short-circuit protection built in; this is a pure disconnect and isolate device, not a circuit breaker. The 24 V DC undervoltage release (UVR) trips the switch when control voltage drops, so it doubles as a safety interlock or emergency-stop element in a control circuit. Two HQ auxiliary contacts signal the main contact position back to the PLC or panel indication.
Front terminals with busbar connection — it's designed to bolt into a power distribution bus, not to land individual cables on each lug. The 70 mm depth, 76.2 mm width, and 130 mm height match the 3VA frame-160 footprint, so it shares the same panel cutout and busbar spacing as the breaker versions in the same family.
