The contactors include auxiliary snap-action switches with silver or gold contacts, integrated PWM modules for electronic coil control, and main contact terminals secured with M10 or M12 screws.

Procedures: The contactors are equipped with a switching state indicator to denote whether the main contact system is switched on or off. The main contact system is designed for loadless switching, with configurations available for disconnect switches and changeover operations.

Norms and Standards: The document specifies minimum distances for installation to ensure safety and proper insulation. These distances vary depending on the model and are critical for maintaining operational integrity and safety.

Recommendations: The document suggests configurations for different applications, including pre-charging contactors for high-load switching and options for customer-specific versions if required. It also highlights the importance of proper torque application on screws to ensure secure connections.

Diagrams and Tables: Dimension diagrams are provided for each model, detailing the physical layout and installation requirements. The diagrams include measurements in millimeters and specify the arrangement of terminals and auxiliary components.

Critical Information: Key parameters include the voltage and current ratings, the type of auxiliary contacts, and the configuration of the integrated PWM module. The document emphasizes the need for correct installation practices, including adherence to specified torque values and minimum distance requirements.

Specifications: The document outlines the terminal connections for various versions of contactors, including control input enable terminals and pre-charging contactor coil terminals. It specifies permissible mounting orientations, allowing for horizontal or vertical installation on a prepared mounting plate.

Mounting Instructions: Contactors can be mounted using either tapped holes for threaded screws or through holes for screws and nuts. Minimum clearances to earth potential or insulating parts must be observed as specified in the dimension diagrams.

Maintenance: CP series contactors are essentially maintenance-free but require regular visual inspections once or twice a year. Defective parts, such as arc chambers or auxiliary switches, must be replaced immediately.

Safety Instructions: The device must be used according to the intended purpose as specified in the technical documentation. It is not suitable for potentially explosive atmospheres without additional safety measures. Tampering with the device is prohibited and can void warranty and liability. Coil suppression is optimized for the contactor's switching behavior, and external diodes should not negatively influence this.

Additional Considerations: Contactors may heat up during operation, so they should be allowed to cool before maintenance. Strong electromagnetic fields can be generated around contactors, potentially affecting nearby components. Improper handling can lead to damage.

For detailed instructions, refer to the operating manuals and safety instructions available online.

Breaking capacity, arc handling or stretched and cooled in arc chambers until the stored energy of the load circuit has been converted into heat and the arc is extinguished.. In order to extinguish the electric arc within a few milli seconds we have incorporated some sophisticated solutions in our contactors. Arc handling is a particular challenge at the moment of switching off. After opening the main contacts, an arc is created while the current continues to flow. The temperature of the arc is 10,000 °C or more. Before the contact pads or even the entire device are thermally destroyed, the arc...
