170M4466

Fuses are safety devices that are used to protect electrical power systems, devices, and applications from overload or with fault currents. Specialty fuses provide an enhanced level of protection, typically designed for specific applications such as high-temperature, high-amp, and high-energy. The 170M4466 electrical fuse is a specialty fuse designed for high-energy applications, providing effective protection from short circuits or other similar faults.

Overview of 170M4466

The 170M4466 electrical fuse is a specialty fuse, rated for a maximum breaking capacity of 63kA, maximum allowable operating voltage of 4kV (6.9kV BIL) and a maximum DC voltage of 1.66kV with an AC voltage rating of 690V. The fuse is designed for Class CC applications and is suitable for high fault current applications, with a very fast response time and high interrupting capacity.

Design Benefits

The 170M4466 electrical fuse offers significant design benefits including:

• Reliability and longevity, with a life expectancy of up to 100,000 cycles.
• High resistance to shock, vibration, and electrical interference.
• Simple installation, with no preload requirement.
• Compact design, allowing for maximum flexibility in system designs.
• Excellent current-limiting capability.
• Excellent electrical insulation properties.
• Approved for use in hazardous locations.

Application Field and Working Principle

The 170M4466 electrical fuse is well-suited for a wide range of high-energy applications including electric motors, circuit breakers, and other applications where safety is critical. The primary function of the specialty fuse is to open or break a circuit once a fault current is detected. The fuse is designed to respond quickly to the high levels of energy released by a fault, essentially acting as a safety switch that will cut off the power to prevent any further damage. The fuse is a one-time device and must be replaced after it has been triggered.

The fuse features an embedded fuse element, typically composed of an alloy wire or ribbon, which provides the sensing, breaking, and current limit elements. The fuse element is surrounded by a metal housing, typically composed of copper or brass, which provides protection against abrasion, moisture, and other environmental damage. The two ends of the fuse element are connected to the internal contacts of the fuse holder, while the fuse body is attached to the holder with two screws.

Conclusion

The 170M4466 electrical fuse is a specialty fuse designed for high-energy applications, providing exceptional protection from short circuits and overloads. With its robust design, reliable performance, and short response time, the fuse is an ideal choice for use in numerous electrical protection applications.
