A relay is a switch; it is not usually meant to open under fault conditions (high current), and would likely fail if done so. A fuse is a fault protection device. If a short circuit develops, large currents will flow, and the fuse link will melt, causing the circuit to open.
There are also protective relays, which are devices that sense fault, or other undesireable conditions, and are used to send trip commands to breakers.

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 is difference between reverse power relay and directional relay in electrical protection?
A reverse power relay is a directional overcurrent relay. Directional relays are relays that sense power flow in one direction, and include (directional) overcurrent relays, reverse power, and impedance based relays. So a reverse power relay is a directional relay, but a directional relay is not necessarily a reverse power relay.

Fuel relay fuse?
can a fuel relay fuse make car not start? If the fuse or the relay is bad, yes.
Difference between overcurrent relay and fuse?
Current is flow of electricity charge. Voltage is a measure of potential energy or charge. Fuse. Is a device that opens when the current rating is exceeded this stopping the flow of current.
Is there a difference between the main relay and the fuel pump relay on the 2000 Honda civic ex?
They are the same relay.
Where is the ac fuse between the fuse box and ac relay on a 77 Chevrolet Malibu Classic under dash or the hood?
There is a fuse for the air conditioner and one for the fan. You have a power source to the fuse. From the fuse the relay gets it's power and then the fan and or the air conditioner compressor.
Is there a fuse between the fuse panel and the fuel pump on a 1998 Isuzu Hombre 4-cylinder?
There should be a relay location(?)
What is the main difference between a relay and a solenoid?
A relay is a switch - a solenoid produces a magnetic field.
Fuse relay location on 1985 325e BMW?
There are several fuse relay switches on your 1985 325 BMW. The fuse relay switches are located inside of the fuse box.
Where is the fuel pump relay switch or fuse located on a 1997 Mercury Villager?
The relay is in the relay box under the hood. The fuse is in the fuse box.
