DC fuse base EFH 22 DC 1P 002570201

Safety and reliability in DC installations

The EFH 22 DC 1P base is a key element ensuring protection in direct current circuits. Designed to work with CH gPV fuse links, it is primarily used in photovoltaic installations, but not only. Its solid construction and compliance with IEC60947-1 and IEC60947-3 standards guarantee safe and long-lasting operation.

Installation and compatibility

Installation is done on a TH 35 rail, which simplifies and speeds up the installation process. This solution is appreciated by both installers and end-users due to its simplicity and speed. The base is designed for fuses with dimensions of 22x58 mm, ensuring compatibility with a wide range of available fuse links. The single-pole design allows for flexible configuration of protection systems.

Operating characteristics and application

The rated current of 100A and the rated DC voltage of up to 1000V make the EFH 22 DC 1P base perfect for demanding applications. The DC-20B operating category means it is adapted to circuits with frequent switching on and off, typical for photovoltaic installations. The optical indicator of operation (none) does not interfere with the quick identification of a blown fuse - a visual inspection of the insert is sufficient. The ambient operating temperature is from -5°C to 40°C, allowing it to be used in various environmental conditions.
