Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value thus protecting the rest of the electrical circuit overloads.
Electrical surge arrester symbol. In most cases when a surge arrester intercepts a power surge it fuses itself to prevent transmission. These arresters are also known as surge protectors or lightning arresters but there are some very small differences between these devices. Surge arresters are installed inside the panels to cancel out the surges. Jic nfpa sample drawing.
Also called a surge protection device spd or transient voltage surge suppressor tvss this class of device is used to protect equipment in power transmission and distribution systems. Fuses and electrical protection symbols. Symbols for the arrester and the capacitor are shown connected to the incoming terminations. A surge arrester is device that intercepts electrical surges and sends the spike to ground before it can hurt a connected device.
Resealing voltage voltage across the arrester at which the follow current is still definitely interrupted after sparkover. Main electrical characteristics of surge arresters are. For consumer equipment protection different products. Similarly the verbiage in the text calls for surge and lightning protection.
Iec 60617 sample drawing. Is a device used to protect the electric circuit and connected devices from the. The one line diagram symbols presented here are commonly accepted symbols. Electrical one line diagram symbols one line diagrams are an important means of communicating the components relationships and connections within a circuit or electrical system.

Maximum continuous operating voltage highest power frequency 50 hz or 60 hz voltage that the arrester can withstand permanently. The main concept of installing a surge arrester is to obtain minimum resistance path to earthing when a fault occurs. A surge arrester is a device to protect electrical equipment from over voltage transients caused by external lightning or internal switching events.
