LA15QS3500128 is a special electronic specialty fuse which can provide over-current protection for power system circuits. Its application field covers a wide range, like DC motor, elevator, air-conditioning, communications equipment, computers and other electrical systems.

This particular fuse type is especially used for protecting DC load circuits powered by batteries in motors, elevators, air-conditioners and other types of equipment. It is also suitable for use in telecommunications equipment, computers and other electrical equipment.

This electronic specialty fuse has a two-pole construction with a rated current of 15A. It consists of an insulating casing, energizing coil, movable contact and bimetal strip. The bimetal strip and energizing coil are connected in series by a copper wire. The casings of the two sets of contacts are insulated.

When the current is below the rated current, the energizing coil remains closed and the bimetal strip has no effect on the contact. As the current trips the preset breakpoint, the energizing coils warm up and start to open the contacts. This will cause the bimetal strip to bend and open the contact. This will cut off the current so that the circuit is protected from overcurrent.

When the current is lower than rated current, the contact will close again and the current will flow as normal again. This ensures that the normal operation of the circuit is not affected by a short circuit.

This electronic specialty fuse is also designed with an indicator to show when the fuse is open. This makes it easier to identify whether the fuse has blown and to determine the cause of the fire.

The LA15QS3500128 can provide reliable and accurate protection and can be used in a variety of applications, making it an ideal choice for all power system requirements. It is also easy to install and is suitable for use in harsh environments as it is shock-proof, vibration-proof and moisture-resistant.
