'Overcurrent protection' is a means of protecting a cable and its load from damage due to an overcurrent. An 'overcurrent' is defined as either an 'overload current' (due to an excessive load) or a 'short-circuit current'. In its simplest form, overcurrent protection is provided by means of a fuse, but it can also be provided by means of a circuit breaker. In the case of high-voltage systems, the circuit breaker is tripped by the operation of one or more overcurrent protection relays which monitor the circuit using current Transformers.

How does an over current relay work?
An over current relay will operate when current exceeds its design rating. This application is intended protect loads or circuits from excessive current.
What is the difference between an earth fault relay and an over current relay?
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
What the three types of over current protection relay and describe the principles of operation?

Why does your ecs fuse keep blowing?
There is either a short to ground or an over current condition in the circuit.There is either a short to ground or an over current condition in the circuit.
What protect equipment from too much current by tripping a switch that breaks the current by stopping the flow of electricity?
In electrical terminology it is an over current device. This could be an electrical breaker. Another form of an over current device is a fuse.
How much is a fob for a dodge avenger?

Can a numerical relay give protevtion to over current over voltage and short circuit current at the same time?
Yes. Most microprocessor based relays that have both voltage and current inputs can provide overcurrent and over voltage protection simultaneously. Short circuit current is the same as overcurrent.
Why reducing current in circuit?
The current in a circuit is reduced to prevent the circuit from over load.
