CB1 series control and protection switchgearDetailed product description：

The CB1 series control and protection switchgear (hereinafter referred to as CB1) integrates the main functions of circuit breakers, contactors, overload relays, and isolators. It has high short-circuit breaking capacity, long service life, good coordination and cooperation characteristics, complete protection functions, high intelligence level, simplified system design, easy installation and debugging, and energy-saving and material saving. It effectively reduces the types, specifications, and quantities of products in motor control systems, solves the problem of coordination and cooperation characteristics between discrete components, and is an ideal basic element in low-voltage distribution and control systems.

The CB1 series control and protection switchgear is mainly used for the control and protection of electric motors with AC 50Hz, rated working voltages of 400V and 690V, and rated currents ranging from 0.15A to 125A. It is suitable for frequent operation control and can connect, carry, and disconnect currents under normal conditions, including specified operating overload conditions. It can also connect and disconnect currents under specified abnormal conditions, such as short-circuit currents, within a specified time.
