That is called a fuse.
A fuse is a protective device, which will interrupt the flow of electricity if it is subjected to a current that is greater than its rating.
Some fuses are designed to handle a large inrush of current and are used in circuits such as air conditioners, where a large amount of current is needed at startup, for a short duration and then current drops to a lower level.
These are sometimes called time-lag fuses.
a device protecting conductors or other equipment in a circuit from an overload/overcurrent situation
According to BS7671:2008, Requirements for Electrical Installations, an overcurrent protection device rated at either 30 A or 32 A is required.
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.
a device protecting conductors or other equipment in a circuit from an overload/overcurrent situation
E a suportação da corrente elétrica, por exemplo: 1 am = 1000ma.AnswerBecause it is an overcurrent protective device -overcurrents are rated in amperes.
breakers and fuses
According to BS7671:2008, Requirements for Electrical Installations, an overcurrent protection device rated at either 30 A or 32 A is required.
By the rating of the overcurrent device.
A circuit breaker is an overcurrent device that can be reset after it has opened.
'Overcurrent protection devices' are used to protect conductors from excessive current flow... a fuse
A 50 amp breaker is an overcurent device.
ELCB is the connection to the direct earth path using protective device.while solid earthing is without protective device.A form of ELCB should be installed when direct earth path of low enough impendance can not be obtained.
A fuse is the simplest protective device for over current in an electric circuit.
It monitors the general balanced overloading and has current/time settings. This is determined by the overall protective discrimination scheme.
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
