SPFJ350.X Application Field and Working Principle
The SPFJ350.X is a specialty fuse designed for high current applications, providing reliable protection for two-phase circuits. This fuse has powerful breaking capability, making it suitable for applications where durable breaks are required. The fuse is also designed to be suitable for a wide range of operating temperatures. It is also able to operate in fixed or automatic alternating current modes.
Working Principle
The SPFJ350.X uses a low temperature, high conductivity silver alloy as its primary fuse element. The silver alloy has a low expansion coefficient, making it ideal for temperature-sensitive applications. The fuse’s internal design is a series of long and thin metal strips which comprise the fuse element and provide paths for current to pass through.
The fuse is designed to function as a time-delay device in the circuit. Under normal operating conditions, current flows uninterrupted. When an overload is sensed, current rises beyond a predetermined level, triggering the fuse to open its contacts and shut off the circuit. The opening action of the contacts releases energy stored within the fuse which contributes to breaking the circuit.
Applications
The SPFJ350.X is ideal for high-current applications. It is used in a variety of applications such as electrical distribution systems, electric motors, relays, transformers, lighting systems, and other power-supply equipment. It is also suitable for appliances that use high power levels such as ovens, air-conditioners, and so forth.
The SPFJ350.X is also used in applications requiring high inrush currents such as switching motors. In these applications, the fuse has the ability to deliver short bursts of extremely high current levels while still providing reliable protection for the circuit.
The wide range of operating temperatures make the SPFJ350.X suitable for many different types of applications. For instance, it is used in cold-weather locations such as refrigeration and freezer systems, in hot-weather applications such as air-conditioners, and in extreme temperature environments such as photovoltaic panels or equipment working in desert or industrial conditions.
Conclusion
The SPFJ350.X offers reliable protection for applications requiring high-current protection, and is suitable for use in a wide range of operating temperatures. It is designed to provide time-delay protection for the circuit, and is ideal for applications with high inrush currents. The SPFJ350.X is a versatile and reliable fuse suitable for a wide range of power-supply applications.
