Description

Motor Protection Circuit Breakers (MPCB) (0.1-45A) are essential for the overload, phase loss, and short circuit protection of three-phase asynchronous motors. The CKDD1 series is designed for circuits with AC voltage up to 690V and rated current up to 45A. This versatile series can be integrated with AC contactors and thermal relays to create a comprehensive motor control and protection system, ideal for frequent startups and control of AC motors.

The MPCB series features two housing frames (32A and 45A) and offers a total of 18 current grades, allowing for calibrated rated currents. Each unit includes a temperature compensation function, ensuring precise matching to motor power requirements. Furthermore, the MPCB comes equipped with lateral and top-mounted auxiliary contacts, alarm contacts, undervoltage trippers, shunt trippers, surge suppressors, and other modules, providing a complete accessory package for enhanced functionality.

This product complies with standards including GB14048.2, GB14048.4, IEC/EN60947-2, and IEC/EN 60947-4-1, ensuring reliability and safety in operation.
