CMC-3A Dense Plug-in Busway

CMC-3A Busway is the first-generation busway product developed by our factory based on the absorption and adaptation of Japanese busway technology.

Branch Busway
　　 For branch currents ≥250A, a branch busway is used to connect with the plug-in switch box, ensuring surface contact effect and greater safety.

Plug-in Box
　　 The plug-in switch box is equipped with an automatic air switch (model can be selected by the user) to ensure branch circuit overload and short-circuit protection. Available in specifications of 100A, 250A, and 630A, with set values chosen by the user. We also produce combined distribution and power plug-in boxes.
The plug pins are critical components. Our factory's unique process involves adding two pieces of 65Mn spring steel sheets to the pins, ensuring excellent elastic contact even after more than 200 insertions.
