It switches three poles (3P) and carries a 9 A rating in AC-3 duty at up to 440 V, which covers most small three-phase induction motors up to roughly 2.2 kW on a 400 V line. The 115 V AC coil matches common North American control-voltage standards. Rated for utilisation categories AC-1 (resistive), AC-3 (squirrel-cage motor starting/running), and AC-4 (plugging/inching), so it handles both steady resistive loads and the inrush of motor starting. The single NC auxiliary contact is built in for interlocking or status feedback.
For a typical 400 V three-phase motor, 9 A AC-3 corresponds to roughly 2.2 kW output. The 115 V AC coil draws about 7 VA inrush and 4.5 VA sealed, which matters when sizing the control transformer. Altitude derating starts above 2000 m. Mechanical shock and vibration ratings are specified per IEC 60068-2-27 and IEC 60068-2-6: it withstands 15 Gn shocks on Y and Z axes with the contactor closed, and 4 Gn vibration at 5-300 Hz. That is enough for most conveyor and pump applications but not for high-shock press or crusher duty.
It clips onto standard DIN rail and the preassembled reversing busbar saves the wiring step of cross-connecting two contactors. The 3 NO power poles and 1 NC auxiliary are fixed — no add-on contact blocks in this variant. Flame-retardance meets UL 94 V1 and NF F 16-101/102, which is standard for rail and industrial control panels. Protective treatment conforms to IEC 60068 and DIN 50016 for corrosion resistance in mildly aggressive atmospheres.
