Did you know? According to industry data, facilities with modern switchgear systems experience 70% fewer unplanned outages compared to those with outdated equipment.
What Is Electrical Switchgear?
Electrical switchgear is a collection of electrical disconnect switches, fuses, and circuit breakers used to control, protect, and isolate electrical equipment in power systems. Think of it as the command center of your electrical infrastructure – it’s where power gets distributed, monitored, and safeguarded against potential hazards.
At its core, switchgear serves three primary functions: it controls electrical power flow, protects equipment from electrical faults, and provides isolation for maintenance and safety purposes. Without proper switchgear, electrical systems would be vulnerable to dangerous overloads, short circuits, and other potentially catastrophic failures.
