Time-lag fuse link DIII gG 50A/500V 002313402

Safety and electrical installation protection

Time-delay fuse link DIII gG 50A/500V is a safety element protecting electrical installations from the effects of overloads and short circuits. Its function is to quickly disconnect the circuit in the event of a dangerous current increase, thus protecting devices and the installation from damage, and minimizing the risk of fire. The time-delay tripping characteristic makes this fuse link particularly well suited for protecting circuits with receivers with high inrush current – e.g. electric motors. This means that the fuse link will not operate immediately during short-term current surges during device start-up, preventing unnecessary shutdowns.

Characteristics and application

The DIII gG 50A/500V fuse link is intended for use in installations with a rated voltage of 500V and a rated current of 50A. The "gG" designation indicates the universal character of the fuse link – it provides protection against both short circuits and overloads. Size DIII defines its physical dimensions and compatibility with appropriate fuse holders. The white color of the housing makes it easier to identify and allows for visual inspection of the fuse link's condition.

For installers and end users

Installation and replacement of the fuse link is simple and intuitive, making it a good choice for both professional installers and end users (after disconnecting the power supply!). Replacing a damaged fuse link with a new one restores the full functionality of the installation protection. Thanks to its solid construction and high-quality materials, the ETI Polam fuse link ensures reliable operation for a long time, minimizing the risk of failures and downtime. It is important to select the appropriate current value of the fuse link for the protected circuit – a value that is too low will cause the protection to switch off frequently, and a value that is too high may damage the installation or devices.
