RDT8-PV DC Fuse

Fuse structure: Composed of an isolator and a fuse link. The moving contact consists of a fuse carrier with a fuse link.

Fuse link structure: Made of pure silver melt, high-quality quartz sand, high-strength fuse, and cylindrical cap contacts.

Usage: Featuring a full range of DC breaking capability, it is used for overcurrent protection on the DC side of photovoltaic power generation and energy storage systems.

Normal Working Conditions and Installation Conditions

● The ambient temperature does not exceed 40℃,the average measured in 24h does not exceed 35℃, and the average measured in a year is lower than the lowest value of the ambient air temperature of -5℃. The air is clean and its relative humidity does not exceed 50% at a maximum temperature of 40℃. You can have higher relative humidity at lower temperatures. For example, at 20℃,the relative humidity can reach 90%. Due to the temperature change occurring on the product body condensation situation must be taken measures.

● The fuse should be installed in a place where there is no significant shaking or shock vibration.

● Pollution level: Level3.

● Installation category:Class Ⅲ.

● The card is mounted on the TH35-7.5 standard guide rail and installed vertically.

● Current correction factor.
