Product details

The Siemens 3VA1110-1AA42-0AG0 is a SENTRON 3VA1 switch disconnector in an MCCB-style housing, rated for 100 A continuous current (Iu) on a 4-pole IEC frame 160 footprint. It provides visible isolation and load-break capability without integral overload or short-circuit protection — it is a disconnector, not a circuit breaker. Rated operational voltage reaches 690 V AC 50/60 Hz and 600 V DC, with an insulation voltage (Ui) of 800 V.

Auxiliary contacts and integration

The auxiliary release is omitted — no shunt trip or undervoltage release is fitted, so remote tripping requires an external motor drive (optional, per the product extension listing).

Frequently asked questions

Where can I buy 3VA1110-1AA42-0AG0 and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ to confirm current availability and pricing; no stock count or price figure is published here.

What are the key ratings of 3VA1110-1AA42-0AG0?

Rated continuous current Iu is 100 A, with 4 poles, max AC operational voltage 690 V, max DC operational voltage 600 V, insulation voltage 800 V, and short-time withstand of 2 kA for 1 s.

What is the depth of 3VA1110-1AA42-0AG0?

The depth is 70 mm, with a width of 101.6 mm and height of 130 mm.

Will 3VA1110-1AA42-0AG0 drop into a panel specified around 5SQ2670-2YA63?

No — the 5SQ2670-2YA63 is a 55 mm deep DIN-rail miniature circuit breaker (MCB) with IP20, while the 3VA1110-1AA42-0AG0 is a 70 mm deep MCCB-style switch disconnector with busbar connections and IP40 front. The mounting footprint, connection method, and protection class differ; rewiring and panel rework would be required.
