ICP-N70T104 Circuit Protection

Fuses play an important role in protecting electrical circuits and devices from excessive currents, and ICP-N70T104 series fuses are specially designed for tank protection applications. This fuse series is made up of multiple types that offer various voltage ratings, current ratings, and interrupt ratings, making it suitable for a variety of applications. In this article, we will take a closer look at the features, applications, and working principle of the ICP-N70T104 series fuses.

Features of ICP-N70T104 Fuses

The ICP-N70T104 series fuses offer a wide range of current ratings from 1A to 63A, and voltage ratings from 600VAC to 150VDC. They are also available in a range of interrupt ratings, including 10kA, 18kA, and 25kA. These fuses are UL recognized, RoHS compliant, and CSA certified. They are also suitable for both indoor and outdoor use, making them ideal for a variety of applications.

The ICP-N70T104 series fuses come in a range of sizes and shapes, including blade, tubular, and encapsulated types. The encapsulated version is particularly useful in applications where the fuse needs to be encased in another material. This prevents the fuse from being accidentally removed or exposed to the elements.

The fuses are also designed to provide reliable over-current protection, and feature a thermal cut-off that trips when the current reaches a certain level. This helps to protect the circuit from damage, and prevents the fuse from sustaining damage due to excessive current. They also feature a built-in test button, which allows users to test the fuse before installation.

Application Field of ICP-N70T104 Fuses

The ICP-N70T104 series fuses are designed for tank protection applications. Common examples include fuel tank, storage tank, and oil tank installations. Other applications include motor protection, generator protection, and protection of transformers, capacitors, and other components.

The ICP-N70T104 series fuses also offer protection against over-currents in power distribution systems, and are suitable for use in residential, commercial, and industrial applications. They can also be used in solar photovoltaic and wind power systems, as well as in other renewable energy systems.

Working Principle of ICP-N70T104 Fuses

The ICP-N70T104 series fuses feature a thermal cut-off that trips when the current reaches a certain level. When the current rises, the wire inside the fuse heats up. This causes the internal contacts to expand, which ultimately causes the fuse to trip. The thermal cut-off also ensures that the fuse will not be damaged by over-currents.

The ICP-N70T104 series fuses also feature a built-in test button, which allows users to test the fuse before installation. The test button is connected to a switch inside the fuse holder, and when pressed, energizes the circuit and causes the internal contacts to vibrate. This vibration tests the integrity of the contacts and verifies that the fuse is not damaged. If the contacts are not functioning correctly, the fuse will not trip.

In addition to these features, the ICP-N70T104 series fuses also feature a re-settable trip indicator, which helps to identify over-currents and provides visual indication when the fuse has tripped.

The ICP-N70T104 series fuses are designed to provide reliable over-current protection, and are suitable for use in a variety of applications. They are UL recognized, RoHS compliant, and CSA certified, and they feature a thermal cut-off, a test button, and a re-settable trip indicator to provide maximum protection for electrical circuits and devices.
