315NH3G-690 is a type of specialty fuse manufactured by several different companies. Fuses of this type are used in a variety of applications, from residential to industrial, due to their high level of protection against over-current, over-voltage, and short-circuit conditions. In addition, they are also commonly used in the automotive industry. The fuse\'s "NH3G-690" designation refers to its two main characteristics - the desired current rating and the type of fuse body housing it.

What Is 315NH3G-690 Electrical Fuses?

The 315NH3G-690 electrical fuse is a type of cylindrical body fuse that has a silver center contact surrounded by a plastic-like material. The fuse has a voltage rating of 650V. This means that the fuse can safely carry a specified load of up to 650 volts without any damage or undue risk of fire or electric shock. The fuse is generally used in circuits which experience large amounts of current or near simultaneous electrical activity, due to the superior level of protection it offers in those scenarios.

Application Fields

The 315NH3G-690 fuse is most commonly used in industrial settings. It’s often used for electric motors, overload relays, and power distribution systems, as well as high-voltage circuit breakers, transformers, and switchgear. Additionally, the 315NH3G-690 fuse is widely used in automotive applications, where it’s employed in a range of products from wiring, starter motors, and lamps to alternators and resistor boxes.

The 315NH3G-690 fuse has a high current rating and is suitable for applications with large current or simultaneous electrical events. Its cylindrical body provides excellent protection against fire, electric shock, and over-current and over-voltage conditions. Thus making the fuse an excellent choice for situations where safety is of primary concern.

Working Principle

The 315NH3G-690 fuse works by interrupting the flow of electricity when it senses an overload or a short circuit. Due to the cylindrical shape of the fuse body, the current is intercepted before it has a chance to reach its destination. The fuse is designed to melt at a predetermined temperature, which effectively interrupts electrical flow and protects the system from further damage.

The 315NH3G-690 fuse is designed with two springs at the top and two on the bottom that holds the fuse in place. Once current reaches a certain level, the fuse\'s body heats up, which causes the contact that connects the fuse body to the wire to heat up. Eventually, this contact turns white and the fuse melts, disrupting the electric flow and protecting the system from further damage.

The 315NH3G-690 fuse is an ideal choice for various high power applications, due to its high level of protection and its affordable price. Its cylindrical body provides excellent protection and makes the fuse safe to use in a wide variety of applications, from household to commercial and industrial. Additionally, the fuse is also UL listed and RoHS compliant, which means it meets the highest safety standards.
