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.
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.
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.
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.
Amperage is used to rate cartridge fuses.
A resistor is used to represent any one of many different components, called loads, that convert electrical energy to other forms of energy. For example, motors, toasters, lamps, radios, televisions, microwave ovens, and electric kettles convert electrical energy to motion, heat, sound, and light.
Yes because they are incandescent-filaments lamps so they are purely resistive loads. Simply ensure the operating voltage is correct.
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.

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.
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.

No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
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.

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.

Fuses are overcurrent protection devices. If voltages get extreme they blow to save other components. So yes in a way they detect electrical energy.
