Circuit breakers
Connect and disconnect circuits. With suitable protection, they can interrupt fault currents within their specified ratings. Their interrupting capability differs from that of a simple switch.

Supports indication, metering, automation, and supervision.
Ordinary technical meaning
A clear category at the center of electrical protection and control.
Switchgear is a standard electrical-engineering term for assemblies and devices used to switch, control, protect, and isolate electrical circuits and equipment. Depending on voltage level and application, the category can include circuit breakers, disconnectors, fuses, protective relays, contactors, busbars, metering, and associated control systems. Not every device or assembly provides every function; its capabilities depend on its design and ratings.
Component basics
Different components perform different jobs.
Switchgear combines switching equipment with protection and control. These are simplified explanations, rather than instructions for selecting or operating equipment.
Disconnectors
Provide an isolation function when open. A disconnector is not automatically suitable for interrupting load or fault current; switching capability depends on the device type.
Fuses & relays
A fuse interrupts a circuit when its element melts under specified conditions. A protective relay detects relevant electrical conditions and can command a circuit breaker to trip.
Busbars & metering
Busbars connect incoming and outgoing circuits within an assembly. Metering indicates quantities such as current and voltage; measuring a condition is distinct from interrupting it.

Quick reference
Common questions about switchgear.
Is switchgear the same as a circuit breaker?
No. A circuit breaker is one type of switching device. Switchgear is a broader term that can include breakers, other switching devices, and associated measuring, protection, and control equipment.
Are all switchgear assemblies the same?
No. Voltage ratings, current ratings, fault-interruption capability, insulation, enclosure design, and intended operating conditions vary. This overview does not determine whether a particular assembly is suitable for an installation.
Does opening a switch prove equipment is safe to work on?
No. Switching off and establishing safe isolation are different tasks. This page provides no operating or maintenance instructions. Qualified personnel must follow the applicable procedures and equipment documentation.
Does this website sell or service switchgear?
No. It offers a short category overview and a separate inquiry about acquiring the domain name. The illustration above is decorative and does not report measurements from a real electrical installation.
