Yueqing Xingpai Electric Co., Ltd. provides you with professional control and protection switch system solutions

The control and protection switch product adopts a modular single product structure, integrating the main functions of traditional circuit breakers (fuses), contactors, overload (or overcurrent, phase failure) protection relays, starters, isolators, etc. It is mainly used in power systems with AC 50Hz (60Hz), rated voltage up to 690V, rated current from 3A to 100A, and adjustable working current from 0.12A to 100A to connect, carry, and disconnect circuits under normal conditions (including specified overload conditions), and can connect, carry, and disconnect circuits under specified abnormal conditions (such as short circuits). The functions are as follows:

a. Equipped with remote automatic control and on-site direct manual control functions
b. Equipped with panel indication and electromechanical signal alarm function
c. Equipped with overvoltage and undervoltage protection function
d. Equipped with phase loss protection function
e. Coordinated time current protection characteristics
f. It has the characteristics of inverse time limit, definite time limit, and instantaneous three-stage protection.
By selecting functional modules or accessories as needed, control and protection of various types of motor loads and distribution loads can be achieved.
In terms of structure and function, the control and protection switch series products are no longer individual products such as contactors, circuit breakers, or thermal relays, but a set of control and protection systems. Its emergence fundamentally solves the various problems of unreasonable control and protection coordination caused by the improper selection of traditional discrete components (usually circuit breakers or fuses+contactors+overload relays), especially overcoming the phenomenon of uncoordinated protection characteristics and control characteristics when combining electrical products with different assessment standards, greatly improving the operational reliability and continuous operation performance of control and protection systems.
Control and protection switches are substitute products for low-voltage electrical appliances such as circuit breakers (CM1, ABB, NS, C45), contactors, thermal relays, fuses, etc. They are upgraded products of the CPS series.
