Product details

SIRIUS 3RT2026-2AV04 — Power Contactor, Size S0

Body dimensions: 102 mm high, 45 mm wide, 144 mm deep (cites:,). That 144 mm depth is the full projection from the DIN rail — check your gland-plate clearance before committing the panel layout. Auxiliary contacts are not included on this variant (cites:) — if you need auxiliary switching, you'll add a separate block or spec the -2AV04 with an integrated auxiliary.

DIN Rail Fit and Wiring

That operating ceiling matters for panels near ovens or in unventilated enclosures — derate the switching frequency if ambient stays above 50 °C.

Frequently asked questions

What is the depth of the 3RT2026-2AV04?

The depth is 144 mm from the DIN rail mounting surface (cites:). That is the full projection — verify your enclosure depth before committing the panel layout.

What wire sizes does the 3RT2026-2AV04 accept?

Main circuit terminals accept solid or stranded conductors from 1 to 10 mm² (cites:,). Auxiliary terminals (if used) accept 2x (0.5 to 2.5 mm²) solid or stranded (cites:).

Where can I buy the 3RT2026-2AV04?

The 3RT2026-2AV04 is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

Will 3RT2026-2AV04 drop into a panel specified around 3RT2016-1AG62?

Both are size S0 SIRIUS contactors with the same DIN rail footprint and 45 mm width (cites:,). The 3RT2026-2AV04 carries higher motor ratings (21 A at 480 V vs. the 3RT2016-1AG62's lower current class), so it fits the same mounting holes and terminal spacing but may require larger conductors for the higher current.
