Almost all electrical systems contain fuses, which are the last line of defense when a fault features in an outlet. In the often-challenging conditions of industrial, marine, mining and agricultural applications, where powerful currents can be encountered, specialty fuses like the 170M3907 can be relied on to provide reliable protection.

Overview of the 170M3907

The 170M3907 fuse is a direct-mount, low-voltage, three-pole, time-delay fuse. It’s especially designed to offer superior safety protection for industrial machines and equipment. Manufactured by Mersen (formerly Ferraz Shawmut) this specialty fuse is able to sustain short circuit currents of more than 120,000 A. The fuse is designed to prevent equipment from damage due to large electrical current surge, and its fast-acting design means that any excess current is detected and cut before damage can be done.

The Mersen 170M3907 is supplied in its own voltage- and current-rated enclosures, and each fuse can be used in either three-phase or single-pole applications. Different size and design configurations are also available, meaning that the 170M3907 can be adapted to fit the needs of a wide range of electrical and industrial applications.

Working Principle of the 170M3907

The working principle of the 170M3907 is based on electromagnetism. As electrical current passes through the fuse element, an electromagnetic force is generated. A bimetallic strip, which is connected to the electromagnet by a pair of magnet arms, is then activated. The variation in the magnetic field is then used to actuate a set of contactors, which cut the current flow if it exceeds a certain threshold.

The 170M3907 specializes in protecting motors, transformers, and other circuit components from excessive currents. The application of this fuse type is especially useful in applications where normal breakers or circuit breakers do not provide enough protection. Its simple design and cost-efficiency make it one of the most popular and reliable specialty fuse used in industrial, marine, mining, and agriculture applications today.

Examples of 170M3907 Applications

The Mersen 170M3907 is suitable for a wide range of applications, including:

• Automotive circuit protection
• High-voltage circuit protection
• Circuit protection in mines and heavy industry
• Circuit protection for electrical equipment in hazardous areas
• Circuit protection for heavy industrial equipment
• Circuit protection for high-power lighting systems
• Motor control applications
• Marine electrical equipment protection

The 170M3907 can provide protection for circuits up to a maximum of 2500 volts. The design of the fuse ensures that it meeds industry safety standards, and it passes all necessary UL tests. It’s also able to operate in temperatures ranging from -55°C to 105°C.

Conclusion

The Mersen 170M3907 is a robust and reliable specialty fuse designed to provide superior protection for industrial machines and equipment. Its highly efficient operation and range of applications make it one of the most popular and versatile fuses in use today. Its simple, cost-effective design makes it easy to install and maintain, ensuring a safe and reliable operation at all times.
