Main Distribution Switchboard (MSB) is a crucial product in industrial electrical systems. If you are seeking basic information about the MSB, don’t miss the article below.
1. Introduction to the Main Distribution Switchboard (MSB)
The Main Distribution Switchboard (MSB), also known as the main electrical panel, main switchboard, or main distribution panel, serves as the input panel for the entire low-voltage electrical system of a facility.
The MSB is typically installed after the low-voltage transformer substations and before the Distribution Boards (DBs).
2. Functions of the Main Distribution Switchboard
The primary function of the MSB is to switch and protect the electrical load sub-systems. The rated current of the MSB can go up to 6300A.
3. Structure of the Main Distribution Switchboard
The MSB is designed with multiple compartments, each serving a specific function such as containing main Air Circuit Breakers (ACBs)/Molded Case Circuit Breakers (MCCBs), load output MCCBs/Miniature Circuit Breakers (MCBs), capacitor banks, Automatic Transfer Switch (ATS) units, remote monitoring via GPRS, etc. Vintec Group manufactures MSBs according to IEC 60439-1 standards, with a rated current of up to 6300A.
3.1. MSB Cabinet
The cabinet is made of galvanized steel and coated with electrostatic paint, available in matte or glossy finishes as per customer requirements. Materials: Electrostatically painted black steel or stainless steel (201, 304). Average height: 200 ÷ 2200 mm. Average depth: 150 ÷ 1000 mm. Cabinet width: 200mm and above. Material thickness: 1.0mm, 1.2mm, 1.5mm, 2.0mm. Common colors: Cream, gray, orange, or the original color of the material. Other parts such as cabinet doors, side panels, and rear panels are easily detachable for user convenience during installation and maintenance.
3.2. Internal Equipment of the Main Distribution Switchboard
Internal equipment is directly sourced from renowned brands like ABB, LS, etc. The internal equipment can be arranged and configured to meet specific customer requirements.
4. Applications of the Main Distribution Switchboard
The MSB is widely used in low-voltage electrical networks and is the most critical component in the power distribution network. MSBs are installed in main electrical rooms of various facilities such as industrial workshops, shopping centers, high-rise buildings, residential complexes, hospitals, schools, ports, airports, etc.
5. Key Features of the Main Distribution Switchboard
Vintec Group’s MSB is designed with modularization, featuring multiple compartments with distinct functions such as load MCCB compartments, copper busbars compartments, loss prevention monitoring compartments, etc. The MSB is designed for convenient and safe operation, allowing quick replacement of equipment without power interruption. Vintec Group’s MSB meets standard mechanical and electrical specifications and requirements. Switching devices, electrical circuits, copper busbars, terminal blocks are logically arranged and labeled, ensuring technical, aesthetic, and safety standards.
6. Where to Buy the Main Distribution Switchboard
With nearly 20 years of experience in manufacturing power transformers, electrical panels, and substations, Vintec Group has established itself as a leading player contributing to the development of Vietnam’s power sector. In addition to core products such as solar energy transformers, high-frequency furnace transformers, single-phase and three-phase oil transformers, Vintec also focuses on manufacturing medium-voltage switchgear panels, low-voltage switchgear panels, ATS panels, MSBs under the Vintec brand. Vintec’s MSB is currently one of the top choices for electrical systems in workshops, factories, residential complexes, hospitals, and various projects nationwide.
