The Siemens 3RT2018-1AK61-Z W96 is a size S00 power contactor from the SIRIUS 3RT2 series, rated for AC-3e and AC-3 duty at 16 A, switching 7.5 kW at 400 V across three poles. That AC-3e rating means it's designed for the higher electrical endurance required when switching standard squirrel-cage motors — the 'e' suffix indicates it meets the extended electrical life test per IEC 60947-4-1, so it's a solid choice for a motor start/stop circuit that sees regular cycling. A single normally-open auxiliary contact is built in, enough for a basic feedback or seal-in circuit. Terminals are screw-type, which is what you expect on a panel-built contactor — reliable, serviceable, no special tooling needed.
