170M6718

The 170M6718 is a specialty fuse type designed to provide overload protection in industrial systems and motors. This fuse is considered undervoltage protection, meaning it is designed to prevent systems from being damaged or destroyed due to improper voltage fluctuations and dips.

The 170M6718 is a dual element fuse, which means it is built with multiple elements that work in combination to protect a system from damage. It is a low voltage fuse operating in the range of 3.3A to 20A, with an AC application range of 30V to 600V. The fuse is designed to cut off power to the system by blowing when the voltage or current within falls out of its range.

While the 170M6718 is designed specifically for motors and industrial systems, it has a range of applications in other circumstances as well. In any situation where power is being supplied to a system that needs to be protected, this fuse should be used. It can be used in residential and commercial lighting systems, power supplies, air-conditioners and power transformers for the same reasons.

Working Principle

The 170M6718 works in two ways: an operating circuit and an overcurrent circuit. In the operating circuit, under normal conditions the fuse is open, allowing for normal operation of the circuit. Should the circuit detect a voltage or current range that exceeds the specified range, the fuse quickly and safely cuts off the power supply, creating an open circuit.

The overcurrent circuit is activated when the voltage or current reaches a peak that exceeds the fuses operating range. This will trigger the fuse to blow, breaking the circuit completely to protect the system from damage. This is considered a sacrificial form of protection, where the fuse is destroyed in order to save the rest of the system.

Conclusion

The 170M6718 is a specialty fuse type designed for overload protection in electric motors and industrial systems. It works in two ways, providing an operating circuit and an overcurrent circuit. The fuse is designed to take the brunt of the damage if the circuit becomes overloaded, blowing to protect the system.
