What Is an Isolator Switch?
An isolator switch is an electrical device used to disconnect a power supply and provide a safe isolation point for maintenance, inspection, or equipment replacement. It is commonly used in switchboards, industrial equipment, and solar PV systems.
Its main function is electrical isolation rather than overload or short-circuit protection, so it is usually used together with fuses or circuit breakers. Isolators are available for both AC and DC applications, while devices capable of switching normal load current are more accurately called switch-disconnectors.

Common Questions About AC and PV DC Isolator Switches
What Is the Difference Between an Isolator Switch and a Circuit Breaker?
An isolator switch is mainly used to disconnect and isolate a circuit for safe maintenance, while a circuit breaker automatically interrupts overload and short-circuit faults.
What Is the Difference Between an AC Isolator and a DC Isolator?
AC isolators are designed for alternating-current distribution systems, while DC isolators use specialized arc-extinguishing structures for solar PV and other direct-current circuits.
How Do I Select the Correct Isolator Switch for a Solar PV System?
Confirm the maximum DC voltage, operating current, number of poles, utilization category, installation location, and required IP protection level.
Can an Isolator Switch Be Operated Under Load?
A standard isolator is mainly intended for circuit isolation and may not be suitable for load switching. A switch-disconnector rated for the relevant utilization category can safely switch normal load current.
What Is the Difference Between an Isolator Switch and a Circuit Breaker?
Normally, isolator switches do not provide automatic overload or short-circuit protection and should be used together with fuses or circuit breakers.
