Fuses actually have a lower resistance that the wire or carrier that is carrying current to and from the fuse. The purpose of a fuse is so that it will burn out before the carrier burns out. When a fuse burns out it breaks the current and therefore no more electricity can pass through it until the fuse is replaced. You gauge the fuse for a little more current than you normally have traveling through the wire. If a power surge of electricity comes through the wire the fuse will burn out instead of damaging the electrical device that is plugged into or wired into the carrier.

What is mazak in regards to fuzes?
Mazak fuses are used primarily on Mazak machine tools. These type of fuses are reusable. They are spring loaded to the fuse wire to ensure fast acting protection. The fuse wire can be replaced.
How much KW range can be use star-delta starter?
The use of a star delta starter is for motor control only and not resistive heating loads. This type of starter is used to dampen the inrush current by using a lower voltage to start the motor.
What type of fuse is used in a motor application?
In motor applications, commonly used fuses include time-delay (or slow-blow) fuses, which can withstand the initial inrush current during motor startup without blowing. These fuses are designed to provide protection against overloads while allowing temporary surges. Additionally, circuit breakers or motor protection relays may also be used to safeguard against short circuits and overload conditions. Selecting the appropriate fuse depends on the motor's specifications and the application's requirements.
What are electrical fuses?
Safety devices used in electrical circuits.AnswerA fuse is an overcurrent protection device, and will operate in the event of a sustained overload current or a short-circuit current.
Which electrical unit is used to rate cartridge fuses?
Amperage is used to rate cartridge fuses.
Can 6o hertz halogen lights be used on 50 hertz?
Yes because they are incandescent-filaments lamps so they are purely resistive loads. Simply ensure the operating voltage is correct.
What is the meaning ampere protection?
Amperes refer to the current in an electrical circuit. Ampere protection is rarely used but it refers to current protection. Typically this will relate to protection against over current events with fuses or circuit breakers.
What does 12 amps resistive load mean?
A resistive load just describes something like a toaster, electric water heater or space heater, where the load is relatively constant. The description is used to distinguish from something like an electric motor, which uses much more current at startup then drops off significantly after it is running.AnswerIn a.c. circuits, a resistive load describes a load whose load current is in phase with its supply voltage. Expressed another way, it is a load having unity power factor. Resistive loads are not necessarily constant -for example a tungsten-filament lamp has a low resistance when cold and a high resistance at its operating temperature.
What types of fuses are used at home?
At home, the most common types of fuses are cartridge fuses and plug fuses. Cartridge fuses are cylindrical and typically found in older electrical systems, while plug fuses are used in fuse boxes and can be easily replaced. Additionally, some homes may utilize circuit breakers instead of fuses, which provide similar overcurrent protection but can be reset rather than replaced. Both types are designed to prevent electrical overloads and protect wiring and appliances.
What are the factors that are used to determine power?
Watts = Volts x Amps x Power Factor Power Factor is one for a resistive load and decreases toward zero as the voltage and current waveforms get out of phase with various inductive loads.
What is mazak in regards to fuzes?

Can you use 110v 60Hz supply for 110v 50Hz equipment?
If the load is non inductive and straight resistive then there is no problem. Inductive loads like motors, a 60 Hz device can be used on 50 Hz but it is much harder on the equipment if 50 Hz is used on a 60 Hz system.

Can parallel circuits be used instead of fuses?
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
Can star delta sarter be used on a three phase fat fryer?
A star delta is used to prevent the across the line current draw when a motor starts. Many utility companies will not allow more than 20 HP to be started across the line. A three phase fryer uses resistive elements in it to heat the oil. Resistive loads must use the full voltage that is recommended by the manufacturer, for the equipment to operate at the recommended wattage that is on the equipment's nameplate.
