Product details

It carries a 14 A rated operational current at 480 V in AC-3 duty — that's the motor-switching current, not the resistive load rating, so size it for the motor FLA, not the contactor's AC-1 maximum. The 45 mm width and 85 mm height fit the standard S0 footprint. Depth is 141 mm, which matters when you're laying out gland-plate clearance in a shallow enclosure.

Wiring and Clearances

For dual-wire terminations, the range is 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). That covers most panel-building scenarios up to about 8 AWG.

Frequently asked questions

What compliance documentation is available for this contactor?

As a Siemens SIRUS product, it carries the standard CE, UL, CSA, and CCC certifications typical for this series. Specific declaration documents (RoHS, REACH) are available on request with the RFQ.
