Fuses play an important role in the electrical industry, and the 5TTP 1.25-R fuses are designed for general industrial use. This type of fuse is used for controlling overload and short-circuit protection in AC power distribution systems. The 5TTP 1.25-R is a time-delayed fuse, meaning that it will take a certain amount of time before it trips when an overload or short-circuit is detected.

The 5TTP 1.25-R offers two different delay times. The first delay time is the "standard" delay time, which is typically 10 seconds. This means that when an overload or short-circuit is detected, the fuse will take 10 seconds to trip. The second delay time is the “delayed” delay time, which is typically 12 seconds. This means that when an overload or short-circuit is detected, the fuse will take 12 seconds to trip.

The 5TTP 1.25-R is suitable for use in a variety of applications, such as: residential service entrance protection, commercial service entrance protection, motor circuit protection, and appliance circuits. It is important to note that these fuses should not be used in applications that require instantaneous or very short delay times. In these applications, a faster responding fuse should be used.

The working principle of the 5TTP 1.25-R fuse is quite simple. When an overload or short-circuit is detected, the fuse element will heat up. This heat builds up until it reaches the fuse\'s melting point, at which point the element melts and causes the fuse to trip. The time delay depends on the size of the fuse element and the ambient temperature. In cooler conditions, the fuse will take longer to trip, while in hotter conditions, the fuse will trip faster.

The 5TTP 1.25-R fuse offers numerous advantages, such as: providing protection against intermittent overloads, providing protection against short-circuits, is designed for easy over-current detection, and features an embedded fuse-body metal indication for easy identification. In addition, this type of fuse is also cost-effective and highly reliable.

In conclusion, the 5TTP 1.25-R fuses are reliable and cost-effective devices that can be used in a variety of AC power distribution systems. They feature two different time delays and are designed to provide protection against both overloads and short-circuits. It is important to note that these fuses should not be used in applications where a faster response time is required. Additionally, these fuses offer numerous advantages, such as being cost-effective and providing easy over-current detection.
