At a glance
The 3RT2018-1AN62: Rated for AC-3 motor duty at 750 cycles per hour max, and AC-1 resistive loads at 1 000 cycles per hour. That's the real switching cadence; don't plan it into a process that cycles faster, or you'll wear the contacts early.
Storage goes down to -55 °C, so winter shipping is fine. Wire termination is screw-type terminals accepting 0.5 to 4 mm² solid or stranded, up to 2x 4 mm². No special ferrules needed; field wire it with standard screwdriver.
Sourcing note
The lifecycle stage is current — Siemens still makes this. No form, fit, or functional replacement needed. We quote it to order against an RFQ; lead time depends on factory load, but it's a standard catalogue line.
