15HLE-150E

Fuses

The 15HLE-150E is a high current fuse manufactured by ABB. It is widely used in industrial and commercial applications. This specific fuse is designed to protect equipment against overcurrents, especially during overload and short circuit conditions. It can also be used in some low-power applications that are powered by direct current.

The 15HLE-150E fuse has a rated voltage of 600 volts and a rated current of 150 amps. It has a time-delay action and a high Interrupting Rating (IR) of 200 kA. Its dimensions are 7.4 x 5 x 5.8 inches (189 x 127 x 148mm). It is UL recognized and CSA certified.

The 15HLE-150E fuse has a wide range of application fields. It is suitable for use in control circuit and heavy load switchgear, motor control centers, and incoming feeders for lighting and industrial areas. It is also suitable for low-consumption electrical equipment, such as computers, communications, and electronics. Additionally, it can be used as protection for components in LED lighting systems.

The working principle of the 15HLE-150E fuse is based on the fact that, when the current passing through the fuse exceeds its rated value, the heat that is generated by the current causes the fuse element to melt or vaporize. This interruption of the current flow blows off the fuse element and stops the flow of electricity.

The fuse also comes with a built-in thermal-magnetic trip device that is designed to provide both thermal and magnetic overload protection. The thermal protective mechanism works by sensing the thermal rise in the winding temperature of the motor, while the magnetic mechanism is designed to detect and open the circuit when the current increases beyond a predetermined value.

The 15HLE-150E fuse is an important safety device and should be used in industrial and commercial applications where a high level of safety and protection from overcurrents is necessary. It is a cost-effective and reliable solution for protecting expensive equipment and providing a safe operating environment.
