FCF35RN

FCF35RN fuses are specialty fuse-links designed for the protection of low-voltage circuits, such as lighting, motor, and the electromagnetic equipment. The specialty fuse could be chosen for its reliability, accuracy, and low price.This type of fuse is composed of a thermally-fused wire loop, consisting of a copper alloy such as manganese bronze, and an electrically-insulated housing. The core of the loop is what provides the current flow, and in a circuit where too much current is drawn, the wire loop will overheat and melt. The thermal fuse is also known as a time-delay fuse, because it is designed to open the circuit within a particular time element after the overcurrent occurs.

The FCF35RN series fuse is designed for the protection of low-voltage (3 to 32V DC) circuits. The current rating is 2.5 to 5 amps and the voltage drop across the terminals is less than 0.4 volts. The number assigned to the fuse is a multiple of its current rating e-g. FCF35RN-2.5, FCF35RN-5. The fuse possesses an epoxy-type terminal construction and could be used in many different applications.

In its application field, a FCF35RN fuse could provide a technique of energy- discharged protection. Unlike a common circuit breaker, a fuse is an electrical device that would protect the circuit against an unsuitable level of current by over-fusing the circuit. The FCF35RN fuse will melt when the current on the circuit reaches a harmful level. This interrupts the circuit and stops the current from exceeding certain levels.

Furthermore, the working principle of the fuse is based on the Joule heating, a form of energy dissipation. It is a form of resistance heating which occurs when current passes through a resistive element. In the case of the FCF35RN fuse, the element comprises a long, thin wire loop of a copper alloy such as manganese bronze which has been insulated to prevent any other current leaking away. When the current passing through the fuse reaches an unhealthy level, heating occurs within the wire loop which causes the wire to melt and consequently open the circuit.

To summarize, FCF35RN fuses are utilized to protect low-voltage circuits from overheating and overcurrent, by melting the wire loop. As a speciality fuse, it is made from a thermally-fused wire loop of a copper alloy such as manganese bronze and an electrically insulated housing. The current rating of the fuse is from 2.5 to 5 amps with a voltage drop across the terminals of less than 0.4 volts. The fuse\'s working principle is based on the Joule Heating, a form of energy dissipation caused by current flowing through a resistive element.
