FAQs
The 82 mm width, 110 mm depth, and 108 mm height footprint fits common DIN rail or panel-mounted installations. Use the 1 N·m tightening torque for the coil terminals and 4 N·m for main terminals to ensure secure connections and reliable operation.
AC-1 current ratings are 105 A at 220/240 V, 125 A at 690 V and 85 A at 690 V for different ambient conditions. AC-3 ratings are 80 A at 415 V, 70 A at 440 V, 65 A at 500 V, 46 A at 690 V, and 80 A for 380/400 V, all at 55 °C or as specified.
Yes. With three main NO contacts and one auxiliary contact, rated for up to 690 V and 125 A (AC-3), it supports direct control of 3-phase motors in conveyors, pumps, fans, and similar equipment, offering reliable switching and scalable control with optional auxiliary blocks.
The product carries CE declarations and UL certification, plus RoHS/REACH compliance. It also features IP20 coil terminals and IP10 main terminals, meeting common safety and environmental requirements for panel-mounted motor starters.
Low coil power loss (AC-3 2 W per pole) reduces thermal load and cooling energy in cabinets, extending component life. The compact block design and accessory compatibility streamline maintenance, shorten commissioning time, and reduce total cost of ownership in high-cycle applications.
