The 3RT6025-1AM00: Rated for AC-3 and AC-3e duty up to 690 V, it handles motor loads up to 23 kW at 400 V at 60 °C ambient, and 40 kW at 690 V at 60 °C. The 690 V rating means it can switch motors on 690 V line-to-line systems common in heavy industrial plants, not just the standard 400 V distribution. Mechanical endurance is rated at 10 million operating cycles typical, with electrical endurance at AC-3 and AC-3e maximum 1,000 switching cycles per hour. At AC-4 (plugging/reversing) the maximum drops to 300 cycles per hour — a real constraint if the application involves frequent inching or reversing under load.
Side-by-side mounting is permitted, so multiple contactors can be ganged without spacing gaps, saving rail real estate. Main and auxiliary/control circuits use screw-type terminals. The main circuit accepts 2x (0.5…1.5 mm²) solid/stranded or 2x (0.75…2.5 mm²), with a minimum 10 mm² conductor at both 40 °C and 60 °C. AWG equivalents are 2x (16…12) and 2x (14…8). Strip and torque per the terminal marking — the screw terminals are field-proven, no special tooling required.
Substance prohibitance date of 05/01/2012 confirms RoHS compliance (EU RoHS recast).
