Electrical, Specialty Fuses

The 170M7290 is an advanced and particularly robust model of electrical fuse. A fuse is an electrical safety device designed to protect both personnel and equipment. Standard fuses are made of a brittle material, which is either wire or strip form. When voltage (or current) above its rated value flows through it, the material slowly melts away. As the fuse element melts, the connection between the two circuit elements is broken, stopping all current flow.

The 170M7290 is used mainly in industrial applications such as motor control, overload protection, and surge protection. It is a UL489 listed device and manufactured according to IEC and CCC standards. Besides, its operation is acknowledged by many major safety standards worldwide, making it a reliable choice for safety-critical circuits.

The 170M7290 is composed of ametal tube-shaped element with a ceramic core inside. The iron-based ferro-alloy of the element is the key element to its safety mechanism. When transitioning through the housing, the element will reach a higher temperature than the surrounding environment. This heats up the ferro-alloy, which lowers its resistance while increasing its current carrying capacity to a safe level. The excess current is drawn away to maintain electrical system safety.

The 170M7290 also offers extended adjustable operating time delay. Increasing the resistance of the ferro-alloy stops the melting process and slows down the temperature increase of the element. This means the fuse can be tailored to suit the current in the circuit, useful for applications that have a varying degree of protection needs. The product comes in various sizes, and 35mm diameter holder ensures assembly with various types of accessories.

The 170M7290 employs an advanced design and build support, giving great protection against shock, vibration, and other environmental factors. This makes it an ideal choice for protection of motors and other electrical equipment in extreme working environments. In addition, it has an excellent contact forming capacity, excellent aging characteristics, and outstanding high breaking capacity.

In conclusion, the 170M7290 electrical fuse offers excellent performance, safety, and reliability for electrical applications. It has been designed to meet relevant standards and offers adjustable time delay, outstanding electrical characteristics, excellent shock & vibration resistance, and high breaking capacity. On top of that, the product is durable and cost-effective, making it a reliable choice for industrial applications.
