What is Low Voltage Switchgear?
Understanding the fundamentals of low voltage electrical distribution systems
Definition
Low voltage switchgear is an electrical distribution system that operates at voltages typically below 1,000V AC or 1,500V DC. It consists of electrical disconnect switches, fuses, and circuit breakers used to control, protect, and isolate electrical equipment in low voltage applications.
Key Components
Circuit Breakers
Automatic switches that protect circuits from overload and short circuits
Disconnect Switches
Manual switches for isolating electrical circuits
Fuses
Protective devices that interrupt excessive current flow
Control Panels
Interface for monitoring and controlling the system
