PTC (positive temperature coefficient) resettable fuses are increasingly becoming popular in countless applications that use low-cost and energy-efficient facilities and equipment. One of the most popular models is the 30R185UPR. This type of fuse utilizes PTC technologies to protect low-current equipment and installations from overcurrents, safely and efficiently.

PTC resettable fuses are designed with an element that only allows low currents to flow through it, instead of just allowing the current to break open. It is composed of intrinsic PTC elements or elements based on semiconductors, that act as a temperature-sensitive switch. The contact is open on a low-current path and is closed on a higher-current one. When an excess of current passes, it reacts by quickly heating up, opening the contact and interrupting the current.

The 30R185UPR model specifically is a PTC resettable fuse that offers performance and economy. Its specifications offer an intermittent rating of 18A, which means the device can hold current for a certain time of 60 minutes with full 18A. Its outer housing is made of anti-flame materials, making it fire-resistant. The timing mechanism used makes it a snap to reset the fuse to its original state once it has cooled down.

When it comes to applications, the 30R185UPR is a suitable choice for inexpensive continuous-duty devices and installations, such as uninterruptible power supplies, telecommunication systems, security systems, consumer electronics, and many other electronic protection applications. Its unique design offers the advantage of cost savings since the fuse is resettable, meaning the consumer does not have to replace the entire unit once overcurrent is detected. This saves not only cost in replacement parts, but also time, making it an ideal choice in application for immediate and cost-effective resetting.

The 30R185UPR operates on a simple principle. When the electrical system is powered up, the PTC resettable fuse is in its initial state, allowing the current to flow. Once the current gets higher than the preset level, the element heats up and opens the circuit, interrupting the flow of current. To reset the device, when the current returns to its normal levels, the PTC fuse cools down and returns to its initial state, allowing the current to flow once again.

Overall, the 30R185UPR is a highly reliable and cost-effective choice for multiple applications that use low-current electronic protection. This PTC resettable fuse has proven its worth in countless applications and has earned itself the reputation of being a successful fuse for various applications.
