Rated for AC-3 duty at 750 switching cycles per hour, it handles motor starting and stopping up to its rated current. The AC-4 rating of 250 cycles per hour covers inching and plugging applications where the contactor breaks the motor at full load. The coil draws 0.24 A at both 50 Hz and 60 Hz, and the contactor is rated for a 24 VDC coil supply. Spring-type terminals on the magnet coil accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capability (2x 0.5...4 mm²).
The AC-3 switching frequency of 750 cycles per hour means this contactor can handle frequent motor starts in conveyor or pump applications without overheating. The auxiliary switch is listed as 'No' — this contactor ships without a built-in auxiliary contact block. If your circuit needs a feedback signal or interlock, you'll add a separate auxiliary switch block (Siemens SIRIUS 3RT19 series).
Integration Notes
These are minimum air gaps for heat dissipation and arc containment — don't cram it tighter in a dense panel. Wire termination: spring-type terminals accept 0.5 to 4 mm² solid or stranded, or 2x 0.5 to 4 mm². Strip length is not listed, but standard spring-clamp practice is 8-10 mm. No auxiliary contacts on board — plan for an add-on block if needed.
