Circuit Breakers Market Overview
A circuit breaker is an electrical safety device designed to protect electrical circuits from overcurrent, short circuits, and other electrical faults. When abnormal conditions are detected, the device automatically interrupts the flow of electricity, preventing potential hazards such as fires, equipment damage, and personal injury.
Circuit breakers are vital components in:
- Residential applications: Protecting home electrical systems and appliances from overloads.
- Commercial applications: Ensuring uninterrupted operations and protecting sensitive equipment.
- Industrial applications: Safeguarding heavy machinery and complex power networks from faults and power surges.
They are categorized based on voltage levels, operational technology, and specific applications: air, oil, vacuum, and SF6 circuit breakers, each designed for low, medium, or high voltage needs.
