The 2070.0021.11 fuses, also known as the US industrial control fuse, is a reliable and well-tested fuse designed for the control and protection of electrical machinery. Built with robust construction, this particular type of fuse has earned its reputation for being an easy-to-install yet reliable source of protection in the industrial control circuit segment. It is available in two variants which have different current ratings and interrupting ratings.

The 2070.0021.11 is a fast-acting fuse which, due to its ability to break circuits quickly, can be used to limit the amount of energy that can be released due to a fault or short-circuit. This fast-acting fuse has the capability to close the circuit quickly enough to limit the effects of an electrical overload without damaging connected equipment. The 2070.0021.11 fuse is temperature and time compensated with a super-rapid response time, making it possible to provide a balanced protection to the components of the circuit, even under variable operating conditions. In addition, the fuse is also designed to minimize installation space as they require only a single location to operate.

The 2070.0021.11 fuses feature a hollow-type construction that utilizes a ceramic holder with a meet-pack construction and a melamine body. This design allows the fuse to remain in position even after the current has passed through, preventing the fuse from becoming loose and compromising the circuit’s protection. This type of fuse has several advantages over other types, such as being watt- and temperature-compensated, as well as being resistant to vibration.

The working principle behind the 2070.0021.11 fuse is simple and intuitive. This type of fuse contains a thin strip of metal that is connected to both the voltage and ground or neutral side. When the circuit experiences an overload or short circuit, the metal strip heats up and releases vapor which causes it to expand. As the metal expands it breaks the connection, thus inhibiting further current flow. In case the overload or short circuit persists, the metal strip can cool down until it once again makes contact with the voltage and ground, allowing the fuse to return to its pre-blown state.

The 2070.0021.11 fuses are used in a variety of applications, including control systems, motor-operating circuits, network power supplies, industrial automation, telecom protection, heavy-duty load protection, and renewable energy applications. This type of fuse is especially useful in industrial-type settings because its fast-acting response time prevents significant damage due to current overloads. Due to its reliable performance and robust construction, this particular type of fuse is highly recommended for use in industrial control systems.
