Abb fuse holder 3P+N 50A DIN rail 1 module M277952

The 50- and 125-A fuse holders have been specially designed for use in any application requiring the protection and isolation of high-current loads: thanks to their compatibility with cylindrical aM and gG fuses, they offer maximum flexibility for the protection of systems with current ratings up to 125A.

The disconnect switch, otherwise referred to as the voltage disconnect switch, has the same as a circuit breaker, but on a larger scale: it is, in fact, responsible for shutting off the flow of power to electrical distribution plants. This serves primarily to ensure the safety of the power plant and primarily of the people working inside it since one of its special features is to separate the flow of energy from working environments. Another special feature of this instrument is its ability to be able to detect defects in the electrical flow and isolate them. When the defect is then corrected, the disconnector will make the current flow normally again.

And suitable for opening and closing circuits under load, providing protection against short circuits and overloads.

It is made of self-extinguishing thermoplastic materials that are resistant to high temperatures, and the contact clamps are made of silver-plated copper.
