Series Overview
Series Overview
- The CPX series switch is a brand - new integrated full - function control and protection switch (abbreviated as CPS). It uses an electromagnetic system as the operating mechanism to drive the contacts to connect and disconnect. It detects the main circuit current through an intelligent control unit, performs logical operations and data processing, and controls the dynamic characteristics of the electromagnetic system to complete fault diagnosis and protection. The CPX switch realizes the main functions of multiple electrical appliances such as circuit breakers, contactors, thermal relays, residual current operated circuit breakers, and motor protectors on a single electrical appliance.
- The switch is suitable for AC 50Hz or 60Hz, with a rated working voltage of 400V and a rated insulation voltage of 1000V. It is used to control and protect circuits or to control the starting, stopping, forward rotation, reverse rotation, etc., of motors. The switch has protection functions such as overload, phase failure, short - circuit short - time delay, short - circuit instantaneous protection, and can also achieve functions such as breaking or three - phase unbalance, residual current protection, over - voltage and under - voltage protection.
- Circuit Breaker Function
- It has functions such as short - circuit instantaneous action and short - circuit short - time delay protection. It can completely break the short - circuit current specified by the corresponding level within 10ms, and the current - limiting coefficient is less than 0.4.
- Contactor Function
- The rated working voltage is 400V, the rated working current is 0.8 - 100A, and no derating is required under the AC44 usage category.
- Thermal Relay and Overcurrent Relay Function
- It has complete, reasonable and continuous three - level protection functions and motor timed start protection function. The overload protection model adopts the currently most advanced double - time constant exponential equation, which can match the allowable overload characteristics of the protected object, and the action is accurate and reliable.
- Motor Protector Function
- Residual Current Operated Circuit Breaker Function
- It has inverse - time residual current protection characteristics.
- Starter Function
- It can replace the starter combined by contactors and thermal relays to control the direct starting of motors.
- Product Life Cycle Pre - alarm Function
- Record and display the cumulative number of operations of the switch during operation.
- Fault Recording and Display Function
- When the system fails, the switch can automatically identify, store and record the fault type and display it, which is convenient for users to troubleshoot.
- Pre - alarm Function
- The pre - alarm function can be turned on or off according to user needs. When the equipment runs over - load and reaches the pre - alarm threshold, the switch sends out a pre - alarm signal, which is convenient for troubleshooting in a timely manner.
- Detection and Display Function
- During operation, it detects the current value, voltage value and residual current value (for L - type products) of the three - phase circuit in real time, and cyclically displays the detection results.
- Phase Failure and Three - Phase Unbalance Protection Function
- Over - voltage, Under - voltage and Voltage Loss Protection Function
