Product Launch: SJKCPS Series Control and Protective Switching Device (CPS)

     The Control and Protective Switching Device (CPS) innovatively integrates motor control and circuit protection functions into a single compact unit. The SJKCPS series is designed for AC380-400V/50-60Hz systems, offering an adjustable overload protection range from 0.4A to 125A, perfectly matching motor loads from 0.12kW to 55kW. This series combines electronic trip functionality and complies with various utilization categories including AC-42, AC-43, and AC-44, providing precise and reliable control and protection for equipment such as pumps, fans, and compressors. Its integrated design fundamentally simplifies the complex wiring associated with traditional separate contactor and breaker installations.

     The core advantage of the SJKCPS series lies in its exceptional flexibility and protection accuracy. Its electronic overload trip offers a wide-range continuous current adjustment (e.g., 40-100A for model SJKCPS-100), allowing engineers to perform “tailor-made” precise settings based on the motor's actual rated current, avoiding compromises or waste due to fixed current steps. The product's compatibility with control power supplies as low as 80V enhances its applicability in various industrial control environments. Its integrated protection includes not only overload but also reliable short-circuit protection, establishing a complete safety barrier within a single device, significantly improving system reliability and safety.
