What does it mean to install CCX3 II 400A?

It's not a tray, it's a 400A busway.

Strong current generally refers to the alternating current voltage above 24V. For example, the voltage of electric lights, sockets, etc. in the home is 110V 220V. Lighting fixtures, electric water heaters, heaters, refrigerators, televisions, air conditioners, audio equipment and other electrical appliances in household electrical appliances are all strong electrical equipment.

Electronics are divided into two parts: strong electricity (electricity) and weak electricity (information). The two are both related and different, generally speaking, the processing object of strong electricity is energy (electricity), which is characterized by high voltage, high current, high power, low frequency, the main consideration is to reduce loss and improve efficiency, the processing object of weak current is mainly information, that is, the transmission and control of information, which is characterized by low voltage, small current, small power, high frequency, and the main consideration is the effect of information transmission, such as the fidelity, speed, breadth, and reliability of information transmission. Generally speaking, weak current engineering includes television engineering, communication engineering, fire engineering, security engineering, imaging engineering, etc., as well as integrated wiring engineering for the above projects.

Weak electricity is for strong electricity. Strong current = (380 220), high voltage does not matter.

In the power system, the voltage below 36V is called the safety voltage, the voltage below 1KV is called low voltage, the voltage above 1KV is called high voltage, and the line that directly supplies power to the user is called the distribution line, if the user voltage is 380 220V, it is called the low-voltage distribution line, which is the strong electricity in the home decoration (because it is the highest voltage used in the family). Strong current generally refers to the alternating current voltage above 24V. For example, the voltage of electric lights, sockets, etc. in the home is 110V 220V.

Lighting fixtures, electric water heaters, heaters, refrigerators, televisions, air conditioners, audio equipment and other electrical appliances in household electrical appliances are all strong electrical equipment.

The intelligent system is a comprehensive system composed of building equipment monitoring system, security system, communication network system, information network system, automatic fire alarm and fire linkage system, etc., for the purpose of centralized monitoring, control and management; The lines of various data collection, control, management and communication control or network systems in the home are called intelligent lines (that is, weak current in home decoration). Weak current generally refers to DC circuits or audio, ** lines, network lines, ** lines, and DC voltages are generally within 24V. Signal input in household appliances, computers, televisions (cable TV.

Three-phase five-wire system, rated current 630A, rated voltage 400V, no unified regulations, protection level IP40, the front is the manufacturer's model;

Modern high-rise buildings and large workshops require huge amounts of electrical energy, and in the face of the hundreds or thousands of amperes of strong current required for this huge load, safe and reliable conduction equipment is selected, and the bus system is a good choice. The busway system is a power distribution device that efficiently transmits current, especially for the economical and rational wiring of taller and taller buildings and large-scale factories.

The rated voltage is 400V, the rated current is 630A, the three-phase five-wire system, the protection level is IP40, the front is the manufacturer's model, there is no unified regulation, the manufacturer decides.

400*250, can be adjusted according to the actual situation.

Which manufacturer's products have product manuals, which have specifications and sizes, according to the size of the busbar.

CCX3 is the model.

2500A is the rated current.

4 is to represent the 4 poles, and it should be clear whether the 4-pole equal section or the n-pole cross-section is half of the phase line.

Three-phase four-wire 2500A dense busway.
