170M3362

Modern technology has led to a great increase in the complexity of electronic devices, which in turn have created a demand for reliable and efficient insulation and protection from electric currents and potential short circuits. Specialty fuses are designed to address this need. The 170M3362 from Littelfuse is a UL listed, time-delay supplemental fuse designed to protect electric circuits and equipment against overcurrents. In this article, we will discuss the application field and working principle of the 170M3362.

Application field

The 170M3362 is a time-delay supplemental fuse designed to protect against overcurrents in electronic circuits. It is ideally suited for applications that require a higher current rating than what is available with standard circuit protection fuses, such as telecommunications, motor control, and fire alarm systems. It is also suitable for protection of AC motor branch circuits, as well as branch circuits that run inductive loads. The 170M3362 has a voltage rating of 600VAC or 250VDC, and can interrupt up to 100,000A at 600VAC.

Working principle

The 170M3362 works by allowing current to flow up to its interrupt rating for a preset time before it opens the circuit. This time delay is adjustable, allowing for a wide range of applications. The fuse consists of two fusible elements, one rated at 100A and the other rated at 10A. The main element is a spring-loaded, helically wound, fusible link that is designed to open when the current reaches the preset level. The secondary element is a low-resistance, non-fusable resistor that is designed to reduce the voltage surge on the fuse links when the current is interrupted. The fuse also has an operating temperature of -55°C to 125°C, and is housed in a molded body, adding to its durability.

Advantages

The 170M3362 offers a number of advantages over standard circuit protection devices. The adjustable time-delay feature allows the user to fine-tune the settings for each application, ensuring optimal protection. The compact size of the fuse makes it easy to install in tight spaces, and the molded body provides superior protection against vibration and shock. The fuse also has a high interrupt rating, which means that it can be used to protect against higher current surges without breaking.

Conclusion

The 170M3362 from Littelfuse is an ideal solution for protecting electronic circuits and equipment from overcurrents. The adjustable time-delay feature and high interrupt rating make it suitable for a variety of applications, and the compact, durable design ensures that it can withstand harsh conditions. The fuse is UL listed, making it a reliable and safe option for electric circuit protection.
