The marine distribution box is made of cold-rolled steel plate with surface spray treatment, which complies with CB/T1046-92 and GB/T1046-92 standards. Suitable for ship electrical networks below 380V/50Hz, 440V/60Hz, or 220V, mainly used for lighting and power distribution. Safe power distribution is achieved through multiple branch circuits, equipped with protective components such as circuit breakers and fuses, with overload, short circuit, and leakage protection functions to ensure the safety and reliability of the power system.

The main functions include:
1. Power Distribution: The electrical energy from the main distribution board (or power source) is safely distributed to various electrical equipment on board the ship through multiple branch circuits.
2. Zoned Power Supply: It enables independent power supply to different areas or types of loads (such as lighting and power) on the ship, making it easy to manage and maintain.
3. Protection function:
a. Overload Protection: prevents damage to the circuit or equipment due to prolonged current exceeding the rated value.
b. ShortCircuit Protection: Quickly cut off power in the event of a short circuit in the circuit to prevent the accident from escalating.
c. Leakage Protection (some models): detects the leakage current in the circuit and acts when it reaches the set value to prevent electric shock accidents and electrical fires (this function is available for some models).
4. Ensuring Safe and Reliable Operation: By utilizing the aforementioned allocation and protection functions, the overall safety and reliability of the ship's power system are ensured.
