Optimal Dimensions and Customization: Standard dimensions of 500mm x 450mm x 700mm, with customization options available to meet specific installation requirements.
Robust Electrical Specifications: Capable of managing a maximum current of 1000A, making it ideal for high-capacity solar energy systems.
High Protection Standard: With an IP65 rating, the cabinet is dust-tight and protected against low-pressure water jets, suitable for both indoor and outdoor environments.
Extreme Temperature Resilience: Operates effectively within a temperature range of -40°C to +60°C, ensuring performance stability under extreme weather conditions.
Advanced Safety Features: Includes internal safety isolation and an over current protection device to safeguard battery systems against electrical hazards.
Cabinet Chell
The cabinet is usually made of metal or plastic. It serves to protect the internal electrical components and isolate them from the external environment. It has a certain level of strength and protection rating, which can prevent dust, moisture, etc. from entering, ensuring the normal operation of the internal components.
Electrical Components
Circuit Breaker: It is an important protective component in the distribution box. It is used to cut off the circuit. When faults such as overload, short - circuit, or undervoltage occur in the circuit, it can automatically trip to protect the safety of the lines and equipment.
Residual Current Device (RCD): It is mainly used to detect the leakage current in the circuit. When a person gets an electric shock or the line leaks electricity, it can quickly cut off the power supply to ensure personal safety.
Contactor: It is used to control the on - off of the circuit. It can realize the start - stop control of equipment such as motors. Moreover, it can cooperate with thermal relays to provide overload protection for motors.
Relay: It can perform functions such as signal conversion, amplification, and logical control. It is commonly used in control circuits to meet various complex control requirements.
Fuse
When the current in the circuit is too large, the fuse element melts, cutting off the circuit and providing short - circuit protection.
Busbar
It is used to connect various electrical components and distribute the electrical energy from the power source to different branches. Usually made of copper or aluminum, it has good electrical conductivity and mechanical strength.
Wires and Cables
They are used to connect electrical components and external equipment, transmitting electrical energy and signals. Their specifications and models are selected according to factors such as the load capacity of the distribution box and the usage environment.

Working principle
Electricity distribution: High voltage alternating current input from the power grid enters the busbar through circuit breakers in the distribution cabinet, and is then distributed to different modules of the charging station through circuit breakers in each branch. For example, a portion of the electrical energy is transmitted to the charging module, which converts AC power into DC power suitable for charging electric vehicle batteries; The other part of the power supply control unit and display screen are used to achieve functions such as operation control and status display of the charging station.
Circuit protection: Circuit breakers can automatically cut off the circuit in the event of overload, short circuit, or other faults, preventing the fault range from expanding and protecting the safety of charging station equipment and electric vehicle batteries. When the current is too high, the fuse melts, cutting off the circuit and providing short-circuit protection.
Control and monitoring: The contactors and relays in the distribution cabinet can be controlled to turn on and off the circuit according to the control instructions of the charging station system. At the same time, by installing monitoring components such as current transformers and voltage sensors, real-time monitoring of current, voltage and other parameters in the circuit is carried out, and the data is fed back to the control system of the charging station to adjust the charging parameters in a timely manner, ensuring the safety and efficiency of the charging process.
