258GDQSJ20ES Application Field and Working Principle

The 258GDQSJ20ES is a 20-ampere cartridge fuse designed to provide protection to low-voltage control circuits and other equipment operating at a voltage of up to 600-volts. The fuse is UL Listed and CSA certified for safety and is rated for a maximum of 20-amperes at 600-volts AC. The fuse is constructed from silver alloy and is housed in a thermoplastic body.

The 258GDQSJ20ES fuse is designed to provide protection against short circuit and over-current conditions in low voltage control circuits. The fuse is designed with a built-in safety override feature that will automatically reset itself after the over-current or short circuit condition has been corrected. This feature helps to ensure that the underlying circuit is protected from future occurrences of the same problem. The fuse also features a visual indicator that will alert the user when the fuse has tripped and should be reset.

The working principle of the 258GDQSJ20ES is relatively simple. When the current flowing through the circuit exceeds the rating of the fuse, its internal element will heat up and expand, which will cause the fusible link inside to break and the circuit to be opened. The current will then be diverted to a separate terminal inside the fuse so that it can safely bypass the circuit while the over-current is still present. Once the over-current condition has been resolved, the fuse will reset itself and the circuit will be restored.

The 258GDQSJ20ES is designed for use in low voltage control circuits and can be used in applications such as industrial control circuits, lighting circuits, and instrumentation circuits. The fuse is suitable for use in both indoor and outdoor installations and is designed for easy installation and maintenance. The fuse is compatible with standard fuse blocks and is available in single pole and dual pole configurations.

The 258GDQSJ20ES is a reliable and cost-effective way to provide protection to low voltage control circuits and other equipment operating at a voltage of up to 600-volts. The fuse is UL/CSA listed, features a built-in safety override feature, and is designed for easy installation and maintenance. The fuse is compatible with standard fuse blocks and is available in single and dual pole configurations.
