170E9685 application field and working principle

The 170E9685 fuse is a high-speed circuit protection solution. It is an advanced version of the 170E9683 fuse. It is based on advanced chip and low resistance design, thus can provide comprehensive protection during circuit operation.

This fuse is a complete device with a pleated metal element within a glass housing. It is used for circuit protection and can be available in ratings of 0.0025 to 20 Amps.

In addition to circuit protection, the 170E9685 fuse can also provide transient overvoltage protection. During normal working conditions, it acts as an impedance in the circuit and helps avoid damage to equipment due to overcurrent surges. Under fault conditions, it acts as a switch and immediately isolates the circuit from damage.

The 170E9685 fuse is mainly used in electrical circuits with high-speed operation. It can help protect the circuit from overcurrent, overload, short circuit and other circumstances. It can be found in low-current telecom applications such as high-speed signal line fault protection.

The working principle of the fuse is based on the Joule heating effect. When an overcurrent surge occurs, it causes temperature elevation in the metal element. As the temperature rises, the fuse element will expand and push against the surrounding glass envelope. This causes the envelope to break and the fuse to open.

The 170E9685 fuse has many applications in the electrical industry. It can be used in a wide variety of equipment, such as air conditioning systems, medical equipment, computers and small appliances. In additon, it is also suitable for telecom infrastructure and automotive electronics.

As a reliable and cost-effective solution for circuit protection, the 170E9685 fuse can help ensure reliable operation and extend the life of the equipment. With its high breaking capacity, fast response time and compact design, it is the perfect solution for many types of electrical applications.
