WARNING: Read and follow these precautions before selecting and using fuses. Failure to properly select, install and use fuses can result in serious injury, death or property damage.

Before final fuse selection, always test the proposed fuse in your actual equipment to ensure that the fuse satisfies all your operational and safety requirements.

Safety Precautions When

Selecting and Using Fuses

Be aware that the breaking ability of a fuse will differ

depending on whether the circuit is an AC or a DC circuit. Fuses intended for use in AC circuits should therefore not be employed in DC circuits, and vice versa, as this may result in accidents such as explosion, property damage, and serious injury.

Use the fuses within the specification requirements. Exceeding specification requirements may result in injury, death or fire.

Shut down the power before touching the fuse. Failure to do so may result in electrocution or serious burns.

Consider the effect of the ambient temperature when you use the fuse.

Electrical performance of the fuse may vary depending on the temperatures.

Do not use the fuse where it is exposed to high humidity, corrosive gas, and flammable gases.

Doing so may result in nuisance operations, disconnection of the fuse-element, or explosion.

Use the fuse in a place where the vibration and impact levels are within the specified limits. Exceeding these limits may result in disconnecting the fuse-element.

Do not form the lead when the fuse is 40 ℃ or more. Lead forming when the fuse is 40 ℃ or more may result in disconnection of the

fuse-element because the load is applied to the fuse-element. Do not apply ultrasonic cleaning to the fuse.

Ultrasonic cleaning may result in disconnection of the

fuse-element.

Use sample fuses only for evaluation.

Do not reuse used fuses. Properly dispose of used fuses. Check if the circuit voltage is

large enough for the fuse operation.

When the circuit voltage is too small, the fuse may not operate even though the abnormal current passes through it, because the current decreases due to the increase of the fuse resistance.

When the fuse is used for a life support system or equipment that requires high reliability, more closely examine and evaluate the fuse in actual circuit conditions than is necessary for other general electronic equipment.

When inserting a fuse into a fuseholder, avoid forcing it. This may result in the fuse cracking or contact failure which will significantly reduce its ability to work properly or shorten its life.
