Specifications:
The document outlines specifications for various electrical components, including fuse holders and microswitches. Key specifications include rated voltage and amperage, applicable wires, installation methods, and material composition. The rated voltage ranges from 400V to 800V, and the rated amperage ranges from 75A to 100A.

Installation:
Components can be installed using DIN rails or direct installation. The document specifies applicable fuses and installation hole sizes for different models.

Materials:
The materials used include nickel-plated brass for conductors and iron chromate for covers. Temporary tightening is achieved using bolts.

Options:
Options include insulation boards (HT4017 and HT6017) and fuse holder covers (HC-06, HC-10, HC-15).

Models:
The document lists various models such as 250FH, 250GH, 350GH, 600FH, 600GH, 660GH, and 750GH, each with specific voltage and amperage ratings.

Microswitches:
Microswitch models include Omron SS-5GL, SS-5GLT, SS-01GL, D2F-D3, and D2F-01-03, suitable for GH & GH Series and SPF Series.

Recommendations:
It is recommended to use components at voltage and current values lower than the rated values for safety and longevity.
