The 170M4985 Specialty Fuse is a high power high current specialty fuse designed for voltage surge protection in product applications. It can be used in automotive, mobile, and industrial applications. It is designed to provide reliable protection while having a small footprint and fast response time. The 170M4985 can accept up to 300A peak current, and has an operating voltage range of 6V to 100V DC.

The 170M4985 is composed of two parts, a small ceramic housing and the fuse element. The fuse element is a high-strength copper alloy wire with a high melting point. The base of the fuse is embedded within a ceramic body filled with a pressurized, non-flammable, gas-filled mixture. The body is designed with a small cutout to allow for the fuse element to move freely.

The 170M4985 operates on the principle of thermoelectricity. This means it uses a temperature differential created across the mating surfaces of the fuse element and the body to open or close the fuse. When the current exceeds the rated value, the increase in temperature causes the fuse element to expand and break away from the body, immediately cutting off the current. This allows the fuse to quickly and effectively protect against nearby components from overheating and potential damage.

The 170M4985 is ideal for electrical surge and overload protection applications, specifically when a small form factor is required. It is designed for use in automotive, mobile, and industrial applications, where the presence of high voltages and high currents may pose a risk to the safety of the device. It is well suited for high power IDM systems, such as UPS units, generators, and power supplies. Additionally, the 170M4985 can be used in buses, solar panels, and heavy-duty vehicles.

The 170M4985 offers various advantages, including a small size, high peak current rating, and fast response time. It also offers superior protection against overloading. It has a low contact resistance, high breaking capacity, and long service life. The fuse is also highly resistant to fire, shock, vibration, and other environmental factors. Its robust construction and zinc-dust-filled pressurized ceramic body ensure superior reliability and excellent performance.

In summary, the 170M4985 Specialty Fuse is a high-powered, fast-response fuse designed for voltage surge and overload protection in automotive, mobile, and industrial applications. Its small form factor, high peak current rating, and fast response time make it a great choice for use in a variety of applications. It is designed for high power IDM systems, buses, solar panels, and heavy-duty vehicles. It offers superior protection against overloading and is highly resistant to fire, shock, vibration, and other environmental factors. Its robust construction and zinc-dust-filled pressurized ceramic body ensure superior reliability and excellent performance.
