Installation is straightforward: mount the 3-pole block cont actor in a standard control cabinet, connect the main circuit conductors to the screw terminals with the specified torque, and wire the control coil to the 110 V (50 Hz) or 110–120 V (60 Hz) supply. Include the optional auxiliary contact block if signaling or interlocking is required. Always observe IP20 coil terminals and IP10 main terminals guidelines and secure all connections to prevent loose contacts in operation.
For AC-3 service, the contactor provides rated operational currents ranging from 35 A to 53 A depending on voltage and temperature, with a maximum breaking capacity suitable for cos phi around 0.45 at 440–690 V. It is designed for switching motor circuits where start-stop operations are frequent, offering a balance between thermal performance and mechanical life while maintaining safe control voltages at 110 V 50/60 Hz.
Yes. With 3 main NO contacts and a single NO/NC auxiliary contact, the contactor is ideal for controlling 3-phase motors up to 690 V and for use in control panels requiring signaling and interlocking. Its compact 82 mm width and compatibility with standard CAD files streamline design and installation in MCCs, ensuring reliable motor control in manufacturing lines.
This device is CE and UL listed, with CCC and CQC declarations available for certain regions. It also complies with RoHS, REACH, and WEEE requirements for industrial equipment. The documented DoC and certification traceability allow easy compliance demonstrations during audits and help meet global procurement standards.
ROI improves through reduced downtime due to robust mechanical and electrical design, easier spare-parts sourcing, and faster commissioning aided by CAD downloads and accessory compatibility. The compact footprint allows denser panel layouts, saving enclosure space and enabling more efficient motor control schemes, which translates to lower capital and operational costs over the system lifecycle.
