Working Principle

The 03440405X is designed to protect electrical circuits from overcurrent. It is composed of a latching mechanism and two contacts. When a fault occurs, such as an overload or a short circuit, the contacts automatically open, disconnecting the circuit and preventing further damages. The 03440405X also includes a built-in fuse temperature indicator, which shows the temperature of the fuse. If the temperature of the fuse exceeds a certain level, the indicator turns red, warning that it is time to replace the fuse.

The 03440405X is one of the most reliable and durable fuse holders on the market and is designed to provide reliable performance for long periods of time. It is also easy to install, making it well suited for any industrial application.
