The contactor measures 70 mm wide by 140 mm high by 195 mm deep, occupying a size S3 footprint. Wiring accepts solid conductors from 2.5 to 16 mm² or stranded from 6 to 70 mm² through screw-type terminals. The auxiliary switch is built in, and the magnet coil termination uses screw-type terminals as well.
Rated for 24 VDC coil operation, drawing 6 A at the rated value. The contactor handles up to 850 switching operations per hour under AC-3 duty and 250 per hour under AC-4.
This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
The depth is 195 mm, which is standard for a size S3 contactor footprint.
As a Siemens SIRIUS product, standard compliance documentation including RoHS and REACH declarations is provided with the shipment. Specific UL, IEC, or other certification documents can be requested at quote time.
