Product details

The Siemens 3VA1116-1AA32-0DC0 is a switch disconnector in MCCB design — not a molded case circuit breaker. It carries no overcurrent or short-circuit protection. Its job is safe isolation under load: you close it to connect, open it to disconnect, and it's rated to break full-load current without welding contacts. Rated continuous current Iu is 160 A on a 3-pole frame, with a max AC operational voltage of 690 V 50/60 Hz and a max DC operational voltage of 500 V. This matters for BOM fit: if your line calls for a 160 A disconnect with no integral trip unit, this is the exact SENTRON frame-160 part.

Undervoltage release and auxiliary contacts

Two HQ auxiliary switches (form C) are integrated, giving you status feedback without an add-on module. The main current circuit connects via busbar connection on the front terminals. A motor drive can be added as an optional extension.

Power loss is 38 W maximum at rated load.

Dimensions are 70 mm deep, 76.2 mm wide, 130 mm high — the same envelope as the 3VA1 MCCB family. Mechanical endurance is 15,000 latching cycles.

Frequently asked questions

Where can I buy 3VA1116-1AA32-0DC0 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the difference between this switch disconnector and a molded case circuit breaker like 3VA1112-5EF32-0CA0?

The 3VA1116-1AA32-0DC0 is a switch disconnector with no overcurrent or short-circuit protection — it isolates load under rated current only. The 3VA1112-5EF32-0CA0 is a full MCCB with a TM240 thermal-magnetic trip unit, rated 125 A at 40 °C, and provides LI protection. Both share the same 70 x 76.2 x 130 mm footprint and front-terminal busbar connection, so the disconnect can drop into a panel originally cut for the MCCB without rewiring, but you must verify the upstream protection scheme.

What compliance documentation is available for this part?

The part carries the SENTRON brand and is designed to IEC standards (reference code per DIN EN 81346-2: Q). Specific UL, CSA, or RoHS declarations are not listed in this record; request compliance documentation with your RFQ.
