E 90h fuse holders are suitable for protection against overloads and short circuits. They are available as a simple 1P+N module and as a triple 3P+N module, designed for use with cylindrical gG and aM fuse inserts. The housing is made of self-extinguishing material with high temperature resistance, and the contact clamps are made of silver-plated copper. E 90h fuse holders can be sealed or locked to ensure the safety of operators during maintenance. Versions with fuse failure indication allow for checking the functionality of the fuse.
