Fuses

3414.0117.22 Application Field and Working Principle

Fuses are a common form of overcurrent protection in electrical systems and are designed to protect wires and devices from damage caused by excessive electrical current. They are designed to "break" the circuit and prevent the flow of electricity when the electrical current exceeds a predetermined limit. The 3414.0117.22 application and working principle is primarily used for protecting low-voltage (usually less than 600 volts) alternating current (AC) systems, and current-limiting user-specified applications.When excessive current passes through the fuse, a thin material inside the fuse (usually an alloy of lead and tin) melts, breaking the electrical path and preventing any further flow of current. The 3414.0117.22 application and working principle involves a heat-sensitive device that responds to electrical overloads by melting, disconnecting the circuit and eliminating the risk of electrical fires and other potential hazards.The 3414.0117.22 fuse is a two-pole device that is thermally activated in a vacuum chamber. These two poles are connected to a non-conductive body that contains the thermal elements and a vacuum chamber seal. This design allows for a very fast and reliable disconnect under normal conditions, and — importantly — ensures the fuse will operate reliably even under the most extreme conditions.The two poles of the fuse are placed in direct contact with the thermal elements of the fuse. The thermal element is a resistive material, and when there is an increase in current, heat is generated inside its core. As the temperature of the thermal element increases, it starts to melt, until the point of melting is reached. At this point, the heat melts the non-conductive seal in the vacuum chamber, creating an immediate interruption in the electrical circuit.The 3414.0117.22 fuse is a rapid acting device that is designed to disconnect the electrical circuit in a fraction of a second. When the operating temperature of the fuse is exceeded, the fuse melts quickly, minimizing the damage caused by the overload. This fast operation enables safe disconnection of the circuit faster than any other conventional fuses and fits most international safety standards.The 3414.0117.22 fuse is a thermal cutoff device that is primarily designed as a protective device for low-voltage AC electrical systems. It is used to protect wires, components, and other equipment from possible damage due to an overload or short circuit. The fuse operates in two stages — a slow transition phase during which the current is slowly reduced to the specified value, and a rapid cutoff phase which isolates the electrical circuit and eliminates the electrical current.The 3414.0117.22 fuse is a reliable and cost-effective solution for overcurrent protection. It works effectively to reduce the chances of electrical fires and other hazardous scenarios. It is easy to install, easy to replace, and provides an economical solution for many different applications.
