Product details

Wire termination capacity

The 3RT2018-1AP62: The coil connection uses screw-type terminals — no special crimp tool needed, just a standard screwdriver.

Switching duty and mechanical life

Rated operational current is 10 A at 24 V for the auxiliary contacts, and the main contacts handle 2 hp at 230 V — enough for small motors, pumps, or fans up to about 1.5 kW. The mechanical service life is typical 30,000,000 operations, so it will outlast most machines it gets wired into. For cycling frequency, AC-1 (resistive) allows up to 1,000 operations per hour, while AC-3 (motor) and AC-2 are rated at 750 per hour; AC-4 (inching/plugging) drops to 250 per hour.

Frequently asked questions

What is the closest functional second-source for the 3RT2018-1AP62?

The 3RT2036-1AC20-ZX95 is a larger-frame contactor (Size S2 vs S00) with a different footprint — it will not drop into the same DIN rail space without re-drilling the panel. The 3RT2526-1AF00 and 3RT2526-1AD00 are also different sizes. For a drop-in replacement within the same S00 frame, stick with the 3RT2018-1AP62 or its SIRIUS siblings with the same width and mounting.

What compliance documentation does Siemens provide for the 3RT2018-1AP62?

Siemens provides RoHS and REACH declarations for the SIRIUS contactor range. The product also carries IEC and UL approvals typical for industrial control gear — specific certification marks are listed in the datasheet.
