BUSSMANN WKFHO Series Medium Voltage Fuses
Eaton Bussmann Series medium voltage motor fuses can limit the fault current to a lower level, ensuring that no potential damage has been done to the electrical equipment & motors. They are used in industrial electrical systems for protection against overcurrents and short circuits.

Working Mechanism
- This fuse consists of a thin wire made of material that melts easily.
- When there is too much electricity flowing through the circuit and it reaches a point above the rated capacity, the wire in the fuse heats up and melts.
- This melting breaks the circuit and stops the electricity from flowing.
Features
- Eaton Bussmann Series medium voltage motor fuses offer nickel-plated copper fuse clips for corrosion resistance and high conductivity.
- They feature a striker mechanism to operate the trip bar.
- These medium voltage motor fuses have interrupt ratings up to 50 kAIC.
- They are available in amperage ratings ranging from 250 to 315A.
Frequently Asked Questions
What is the difference between a relay and a fuse?
A fuse can only open the circuit, while a relay can both open and close the circuit.
What is the difference between fuses and MCBs?
A fuse is a metal piece that melts when there is an excess current due to overload, while a circuit breaker has an internal switch that gets tripped when there is excess current in the circuit.
How do these fuses break the circuit?
When an excessive current passes through electrical fuses, the wire inside heats up and breaks, which opens the circuit.
What is the significance of the current rating in a fuse?
The continuous flow of the highest amount of current that a fuse can handle without melting is the current rating of the fuse.
What is the difference between a circuit breaker and a fuse?
A fuse melts when there is too much current, while a circuit breaker trips when there is excessive current or a short circuit.
