0217.400HXP

Fuses are important components of the electrical system that protect circuits from overload and overcurrent conditions. While the type of fuse used depends on the application, the 0217.400HXP is a common shape size for many uses. This article will discuss the application field and working principle of this fuse type.

Application Field

The 0217.400HXP fuse is applicable in a variety of fields, ranging from low voltage DC circuits to high-current AC circuits. It is a great choice for circuits that carry high inrush currents or high-power loads. It is also an inexpensive, easy-to-use solution in automotive and appliance applications that require fast-acting, high-breaking capacity protection. Additionally, these fuses are UL recognized and when properly connected, can meet UL13 requirements.

Design

The 0217.400HXP fuse is a cylindrical shape with two contact terminals. It has a minimum diameter of 0.217 inches and a maximum diameter of 0.4 inches. The fuses are available in various amperage ratings ranging from 1A to 30A. It has a fast response time designed to quickly trip when overloaded or short circuit current is detected. The fuse elements are made of Nickel-Chromium alloy and have a 10x minimum life expectancy.

Working Principle

These fuses operate under the principle of “over-current protection”. This means that the fuse will protect the circuit by limiting the current to a safe level. The select amperage rating of the fuse is predetermined and tested to trip at a certain level. For example, the 30A 0217.400HXP fuse is designed to trip at 32A. When the circuit runs a current exceeding the amperage limit, the fuse element will heat up and quickly melt, breaking the circuit in the process.

Advantages

The design and construction of these fuses give them many advantages. They are inexpensive to produce compared to higher quality alternatives. The fuse element is highly responsive and quickly trips in the event of an overload or short circuit. It also has a fairly long life expectancy, typically 10x the amperage rating. They are also UL recognized and provide reliable protection.

Conclusion

The 0217.400HXP fuses are designed for a variety of applications ranging from low-voltage DC circuits to high-power AC circuits. They are UL recognized, cost-effective, and have a fast response time designed to quickly trip in the event of an overload or short circuit. The fuse element is made of durable Nickel-Chromium alloy, giving it a long life expectancy. For these reasons, 0217.400HXP fuses are an excellent choice for electronic circuits needing reliable protection.
