The JJS-125 fuse is an electrical fuse with a specialty application. This fuse is typically used in power utility, electrical transformer installations, and even industrial applications. It is designed to protect against short-circuiting, overload, and low-level circuit faults. The fuse also provides protection against reverse polarity.
The JJS-125 fuse has a standard mounting pattern of 5.30 inches. It has a maximum voltage rating of 125 volts AC and a maximum current rating of 10 amperes. It is rated for a minimum operating voltage of 125 volts and a maximum operating voltage of 1500 volts. It is temperature-rated for -55°C and 105°C.
The JJS-125 fuse utilizes thermal and magnetic characteristics to provide short-circuit protection. The fuse utilizes a metal oxide varistor with a time delay characteristic. This varistor is designed to accumulate heat before it trips. This time delay provides additional protection against surge currents.
When the current through the JJS-125 fuse exceeds 10 amperes, the varistor heats up and causes the fuse to trip. When the current reaches 15 amperes, the fuse is designed to immediately trip off without the need for the time delay. This provides fast circuit protection and helps to prevent damage to connected components.
The JJS-125 fuse also provides protection against reverse polarity. When a reverse polarity voltage is applied to the JJS-125 fuse, the varistor senses the changed voltage polarity and trips the fuse before current can flow. This helps to protect equipment connected to the circuit from damage.
The JJS-125 fuse is UL listed and widely used in industrial, electrical transformer, and power utility applications. It provides fast protection against short-circuit, overload, and reverse polarity. Its time delay feature also provides additional surge protection. The JJS-125 fuse is a versatile, reliable, and cost-effective solution for electrical protection applications.
