170M2657

Electrical components such as fuses are essential for safe electrical systems. Fuses protect electrical circuits from damaging short circuits or overloads. The 170M2657 is a specialty fuse specifically designed for switching applications. This article will discuss the application field and working principle for the 170M2657.

The 170M2657 is a medium voltage Class H fuse rated for 600 volts AC with a current rating of 57 amps. It is UL listed and meets the requirements of US National Electric Code (NEC) Class H, K5 and RK5. The fuse can be used in a variety of applications including motor circuit protection, high-speed switching, and power panel applications. It is also suitable for use in both series or parallel configurations.

The 170M2657 has an interrupting rating of 200,000 RMS amps, making it suitable for high current applications. It is protected by a resealable fuse holder or a standard DIN rail. The fuse is available with time current characteristics from 20 sec at 65% rated current to 0.20 sec at 6000 amps. The time current curve accurately monitors the amount of current passing through the circuit.

The 170M2657 works by limiting the amount of current that passes through the circuit. When the current exceeds the specified value, the fuse element melts, interrupting the power supply. The melting of the fuse element is known as tripping and helps to prevent the circuit from operating at unsafe levels. The time current curve of the fuse ensures that the circuit does not operate at unsafe levels when tripping occurs.

The 170M2657 is an ideal solution for a range of applications. Its interrupting rating, features, and high current rating make it suitable for applications involving high voltage and high currents. The fuse also offers accurate time current characteristics, providing precise monitoring of current passing through the circuit.

In conclusion, the 170M2657 is a specialty fuse designed for switching applications. Its UL listing and compliance with NEC Class H, K5 and RK5 requirements make it suitable for a wide range of applications. The fuse’s interrupting rating, features, and time current characteristics make it an ideal choice for applications involving high voltages and high currents.
