FAQs
Yes. The block contactor is rated for main and auxiliary circuits up to 690 V AC, with a rated control voltage of 48 V at 50/60 Hz, making it compatible with standard European and North American three‑phase motor installations.
The device provides AC‑3 rated current specifications that vary with voltage and temperature; for 690 V operation at 40 °C, Ie is 100 A, with de‑rating at higher temperatures (e.g., 70 °C reduces Ie). Specific values are listed in the datasheet and must be consulted for exact operating points in your application.
Key certifications include CE Conformity, UL Certificate, and RoHS compliance. These attest to safety and regulatory compliance for European, North American, and environmental standards, reducing compliance risk for product launches, OEM approvals, and cross‑regional deployments.
Install with screw terminals, follow the specified tightening torques (Main circuit 4 N·m, Control circuit 1 N·m), and respect IP ratings (coil IP20, main IP10). Use appropriate auxiliary contact blocks if needed and verify the device is mounted in a ventilated cabinet within the ambient temperature range to prevent overheating.
The combination of high‑current AC‑3 capability, compact footprint, optional auxiliary contacts, and robust electrical life reduces panel size, wiring time, and downtime. This translates to lower installation costs, faster commissioning, and improved machine uptime—delivering a favorable total cost of ownership for OEMs and maintenance teams.
