170M3739

Electrical components are essential for modern life. Whether it is to control lighting, to power electronics, or to run a factory, the components provide a way to safely bring power to everyday objects. Fuses, in particular, provide a critical function of protecting circuits from overloading. Specialty fuses, such as model 170M3739, are designed to provide more specific functions and protection than traditional fuses.Model 170M3739, manufactured by Eaton, is a three-pole fuse designed for protecting AC or DC circuits from dangerous overload conditions. It is UL rated for 1000 volts DC maximum. It has a 200 amp thermal limit and a 400 amp melting limit, so it can handle up to 600 amps for short overload conditions (where the overload exceed 200 amps for a short time).The 170M3739 is designed for use in telecommunications, industrial, and commercial applications. It can be used to protect main AC circuits, DC circuits, and other circuit applications. It allows for optional mounting of two fuses in one compact three-pole unit, providing more protection points in a smaller size.The model 170M3739 uses a bi-metallic strip made of copper and brass to act as the contacts. When power is applied to the fuse, the current flowing through the fuse will heat up the bi-metallic strip. As this heat builds up, the strip will either bend or break, depending on the current load. This causes a physical disconnection in the circuit, cutting off the power supply and providing protection against overloading.Upon disconnection, the fuse can be reset and re-applied to the circuit. The bi-metallic strip will reset itself when it cools, allowing for reuse of the fuse again. This makes it more economical and efficient than having to replace traditional fuses after every use.The 170M3739 is a specialty fuse that provides superior protection for AC and DC circuits in telecommunications, industrial, and commercial applications. With its bi-metallic reset strip, it is designed to be reused, providing an economical solution that allows for multiple uses before replacement.
