Product details

The coil draws 6 A at 24 V rated value, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V, so the control transformer and wiring need to be sized for the pick-up current.

The contactor footprint is 45 mm wide, 57.5 mm high, and 73 mm deep — a compact S00 frame that fits tightly in a crowded enclosure. The operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, and pollution degree 3 means it's rated for industrial environments with conductive contamination.

Wire sizes accepted: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm² solid or stranded. At 40 °C the minimum permissible cross-section is 4 mm²; at 60 °C it's 2.5 mm². The mechanical life is typical 30,000,000 operations, and the maximum switching frequency at AC-1 is 1,000 1/h, at AC-3 it's 750 1/h, at AC-4 it's 250 1/h — so it's designed for frequent cycling in automated lines.

Frequently asked questions

Where can I buy 3RT6018-1AP02?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional second-source for 3RT6018-1AP02?

The closest peer is 3RT6017-1KF42, which is also a SIRIUS size S00 contactor but with a different coil voltage and terminal style. The 3RT6018-1AP02 uses screw terminals and a 24 V coil drawing 6 A; the 3RT6017-1KF42 uses spring-cage terminals and a different coil. Both share the same S00 frame and DIN rail footprint, so they can swap in the same panel space, but the coil supply and wiring method differ.

What compliance documentation does Siemens provide for 3RT6018-1AP02?

The part has a substance prohibition date of 05/01/2012, indicating RoHS and REACH compliance. Siemens provides a declaration of conformity and UL/IEC certifications for this SIRIUS contactor.
