Product details

IP20 on the front, IP00 at the terminals — so the contactor is protected against finger contact on the front face, but the terminal area is open and must be housed inside an enclosure.

Screw-type terminals on the main current circuit accept solid conductors 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max. 2x (0.75...4 mm²); stranded with ferrule 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²); and AWG 2x (20...16), 2x (18...14), 1x 12. Main circuit stranded accepts 2x (1...2.5 mm²), 2x (2.5...6 mm²), max. 2x 10 mm². Auxiliary contacts use the same AWG range as main contacts.

The contactor has zero normally-closed main contacts, so all four poles are normally-open — typical for motor switching where the load is disconnected on de-energization.

Environmental and life ratings

Maximum operating altitude 2 000 m. Mechanical life typical 10 000 000 operations. The contactor is rated for 50 Hz only (the listed rated frequency).

Frequently asked questions

Who supplies 3RT1326-1AV00 and how is it quoted for volume purchases?

The 3RT1326-1AV00 is supplied through independent distribution channels. It is quoted to order against an RFQ; availability and current pricing are confirmed at quote time.

What is the closest functional second-source to 3RT1326-1AV00?

The closest functional peer within the same SIRIUS family is the 3RT1026-1AB00. Both are size S0 power contactors with four main poles, screw terminals, and similar mounting. The 3RT1326-1AV00 is rated for 11 kW at 400 V AC-2, while the 3RT1026-1AB00 is a lower-current variant — check the specific AC-3/AC-2 rating of the 3RT1026-1AB00 to confirm fit for your load.

What is 3RT1326-1AV00's listed depth?

The listed depth is 91 mm.

What is the solid conductor range for 3RT1326-1AV00?

Solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max. 2x (0.75...4 mm²).

Will 3RT1326-1AV00 drop into a panel specified around 3RT1023-1AL20 without rewiring?

Both are size S0 contactors with screw terminals, so the physical footprint and mounting rail are the same. However, the 3RT1326-1AV00 has four main poles (4 NO), while the 3RT1023-1AL20 has three main poles — if your panel wiring expects a 3-pole contactor, the 4-pole 3RT1326-1AV00 will not drop in without rewiring the main circuit.

What compliance documentation does Siemens provide for 3RT1326-1AV00?

Siemens SIRIUS contactors typically carry CE, UL, CSA, and RoHS/REACH declarations. The evidence for this specific order code does not list individual approvals, but the SIRIUS series is generally certified for IEC/EN 60947-4-1 and UL 508. Request the specific declaration at quote time.
