3414.0113.22.M application field and working principle

Fuses are protections devices used in electrical circuits to prevent against overloads and short circuits that can cause damage to or destruction of electrical equipment. The 3414.0113.22.M is an auto-reclosing fuse that provides general protection for single phase installations in industrial settings, making it applicable for residential, but better adapted for commercial and industrial uses. It uses two alternating connections housed in an anodized aluminum casing for increased durability and insulation against shock.

The 3414.0113.22.M is an auto-reclosing fuse that involves a clearly distinguishable current-limiting facility that can interrupt overload and short-circuit within a range of 2 to 150A. It also features an adjustable pick-off current of 1.25mm² to 10mm². To improve its overall impact strength and insulating capabilities, the use of strong, fiber-reinforced resin and ceramic materials are incorporated into its design in order to provide high levels of protection and safety. It can withstand temperatures ranging between - 25°C and + 85°C.

When exposed to either an overload or a short circuit, the primary fuse element of the 3414.0113.22.M will react and open in order to eliminate the dangerous condition. It then allows for follow-up currents of the same magnitude as the primary current, provided that they are within the pre-set limit, to pass. This feature is the one that allows the fuse to be auto-reclosing after a given period of time. This fuse element consists of a metal strip that melts when the current exceeds the pre-determined level set by the user, automatically breaking the circuit and opening the switching unit, should the current still exceed the set level after the re-closing process.

The 3414.0113.22.M is thus intended for indoor or outdoor general protection of single phase installations from overload and short circuits, providing a very good alternative to traditional protective relays or circuit breakers. Its primary function is to protect wiring systems from overcurrent or damage due to excessive current levels. As such, it is an efficient and relatively easy-to-install device that can prove to be extremely effective in providing protection against current levels that could otherwise be disastrous.

In conclusion, the 3414.0113.22.M is an auto-reclosing fuse designed to provide general protection for single phase installations in industrial settings. It has two alternating connections housed in an anodized aluminum casing for increased durability, insulation against shock, and impact strength. Its primary fuse element consists of a metal strip that melts once the current exceeds the pre-determined level, and can be re-closed after a given period of time. The protective device can handle up to 150A, and temperatures of - 25°C and + 85°C. This make it a versatile and reliable protector for electrical circuits, and a good option for residential and commercial and industrial settings.
