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.","metaTitle":"Siemens 3VA1116-1AA32-0BC0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA32-0BC0 SENTRON switch disconnector, 160 A rated continuous current, 690 V AC, 3-pole, with undervoltage release 24V DC and 2 HQ auxiliary switches.

The 3VA1112-5EF32-0CA0 is a full MCCB with a TM240 thermal-magnetic trip unit, rated for fault interruption up to 187 kA at 240 V. Both share the same frame-160 footprint, busbar spacing, and mounting dimensions, so one can replace the other in a panel without rewiring — but the circuit breaker provides protection the disconnector does not."},{"question":"Where can I buy 3VA1116-1AA32-0BC0 and how is it quoted?","answer":"Sourced to order against an RFQ through independent distribution channels.
