Circuit Breakers

  Devices that can interrupt high current flow to protect electrical circuits.

Fuses

Safety devices that protect electrical circuits from overcurrent by melting and breaking the circuit.

Switches

 Devices used to open or close an electrical circuit manually.

Disconnectors

Isolating devices used to ensure that an electrical circuit is completely de-energized for maintenance.

Transformers

Devices that transfer electrical energy between two or more circuits through electromagnetic induction.  

Relays

Electrically operated switches that control a circuit by opening or closing contacts in another circuit.  

Isolators

Devices used to ensure that a section of the electrical circuit is completely de-energized for service or maintenance. 

Lightning Arresters  

Devices that protect electrical equipment from lightning strikes by diverting the surge to the ground.
