Low Voltage Switchgear Manufacturer (≤690V)
for Industrial Power Distribution
Custom Low Voltage Switchgear Solutions for EPC & Industrial Projects
Weimiao specializes in designing and manufacturing low voltage switchgear systems up to 690V, tailored for industrial, commercial, and infrastructure projects worldwide.
Our solutions focus on safe and reliable power distribution, supporting complex electrical networks from main power intake to sub-distribution across facilities.
We provide project-based switchgear systems, not standard catalog products, ensuring every panel is engineered according to your drawings and specifications.
What Is Low Voltage Switchgear?
Low voltage switchgear refers to electrical panels used to distribute, control, and protect power systems within facilities operating at voltages up to 690V.

Core Functions of Low Voltage Panels
-
Power distribution from main supply to different zones
-
Protection against overload, short circuit, and faults
-
System isolation for safe maintenance
-
Reliable operation of industrial and commercial electrical networks
Complete Power Distribution Architecture
From incoming power to end-use distribution, our systems cover the full range of low voltage applications.
Main Distribution Board (MDB)

Low Voltage Switchgear vs Motor Control Systems
Understanding system roles helps ensure the correct solution for your project.
Power Distribution vs Motor Control
-
Low Voltage Switchgear (MDB / SMDB) → Distributes electrical power across facilities
-
Motor Control Centers (MCC) → Controls and operates electric motors
👉 For motor control applications, you may also explore our dedicated MCC panel solutions.
