Siemens SIRIUS 3RT2017-1AH01 — Power Contactor, Size S00
Duty Ratings and Switching Frequency
Switching frequency depends on the duty class: AC-1 (resistive) allows up to 1000 operations per hour, AC-2 and AC-3 (motor starting/running) allow 750 per hour, and AC-4 (plugging/inching) is limited to 250 per hour. The AC-3e rating also caps at 750 per hour. These limits reflect the thermal load on the contacts — exceeding them shortens electrical life.
Mechanical Endurance and Temperature Range
