FAQs
Installation requires mounting the 3-pole block contacor in a standard panel, securing the device with the provided hardware, and wiring the main circuit to the screw terminals. Use a tightening torque of 4 N·m for the main circuit and 1 N·m for the control circuit. Ensure IP20 coil terminals and IP10 main terminals are properly protected within the enclosure.
Rated Operational Current AC-1 ranges up to 115 A at 690 V and 95 A at 220/240 V (40 °C). Rated Operational Current AC-3 includes 65 A at 415–690 V, with corresponding P_e values around 37 kW at several voltages. Short-time withstand and breaking capacities are specified (I_cw up to 1000 A for short times), supporting reliable motor starting.
Yes. The device is designed for 3-phase motor control up to 690 V AC, with main circuit ratings and protective interlocks suitable for high-voltage drive applications. It supports AC-1 and AC-3 operation modes, enabling both switching and starting of varied motor loads in compliant industrial environments.
The AX50–AX80 series provides CE Declaration of Conformity, UL/CSA approvals for North American installations, and RoHS/REACH compliance. Additional certifications include CCC, CQC, and related declarations to support manufacturing and procurement workflows in global supply chains.
The device offers low power loss per pole (6.5 W for AC-1 and 1.5 W for AC-3), which reduces energy consumption and heat in control panels. Its compact form, reliable mechanical life (up to high cycle counts), and CAD-ready data shorten installation time and support faster commissioning, improving machine uptime and total cost of ownership.
