FAQs
Install the 3P block contactor with main circuit connections using copper busbars and ensure proper clearance for heat dissipation. Mount the unit on a rigid panel surface, align auxiliary terminals for monitoring, and verify coil voltage (230–240 V at 50 Hz or 240–260 V at 60 Hz) matches your supply. Use factory wiring diagrams to connect the auxiliary NO/NC contacts for status feedback and interlocking as required.
For AC‑1 service at 690 V, the contactor supports up to 250 A at 40 °C, 230 A at 55 °C, and 180 A at 70 °C. For AC‑3 service, ratings vary by voltage: up to 185 A at 55 °C (with common configurations listed across 415–690 V categories) and related Pe values around 90–110 kW depending on voltage. These figures enable proper sizing for motor start/stop sequences in automation systems.
Yes, it is designed for 3‑phase motor control in industrial drives. Coil options include 230–240 V at 50 Hz and 240–260 V at 60 Hz, providing flexibility for regional power standards. The device supports reliable engagement with a low power loss of about 5 W per pole, helping to minimize heat in control cabinets and improve energy efficiency.
The block contactor carries CE declarations and UL certification, with RoHS and REACH compliance, and a CCC/ CQC presence for certain regions. Documentation covers safe operation, environmental compliance, and market approvals, making it suitable for global deployments in regulated industries.
With a mechanical durability rating of up to 5 million cycles and robust AC‑3/AC‑1 performance, you can expect long service life and reduced maintenance intervals. The compact footprint, low power loss, and predictable replacement cycles translate to lower total cost of ownership, especially in high‑duty conveyor, pump, and processing line applications.
