FAQs
Install the unit in a standard 54 mm wide chassis footprint, connect the three main poles to the incoming/outgoing motor lines using screw terminals, and wire the single NC auxiliary contact as required for interlock or feedback. Use front or side mounting accessories to fit existing control cabinets and add optional auxiliary contact blocks for expanded signaling.
For AC‑1 duty at 690 V, the rated operational current Ie is 55 A per pole; for AC‑3 duty, Ie is 32 A at 415–690 V depending on voltage and ambient temperature. These ratings support starting and running of standard 3‑phase motors in typical industrial loads.
Yes. It is rated for main circuit insulation up to 690 V and supports 50/60 Hz control circuits, with appropriate Ie values for AC‑1 and AC‑3 duty. Its design targets reliable motor control in high‑voltage industrial environments.
It carries CE conformity, UL/CSA recognition, and additional compliance such as CCC, CQC, CB, and RoHS/REACH declarations, ensuring global acceptance, regulatory alignment, and safe material composition.
Consider routine inspection of screw terminals for torque, check auxiliary contact operation, and monitor thermal performance given the 2.5 W per pole rating. With a 7–14 ms coil operate time, plan preventive maintenance to minimize switching wear and ensure consistent performance in high‑demand automation lines.
