ER12-100N3PR

Disconnect Switch Components

The ER12-100N3PR is a high-performance, medium-voltage disconnect switch component used in a variety of industrial and electrical applications. It is designed to be used in outdoor applications and for permanent disconnection of electric current and voltage. The device features a continuous-load rating up to 100 kV and a short-time-load rating up to 5.6 kV. It also has a highly reliable self-reset and is designed for semi-automatic operation.

The ER12-100N3PR disconnect switch component features a magnetic operated contact system that allows for rapid switching of electrical current with minimal arcing. When the magnetic core is pulled away, it creates an open circuit, and there is no electric current passing through the switch. The magnetic core is then attracted back to its original position after the load current disappears, making the disconnect switch automatically reset itself.

In terms of operation, the ER12-100N3PR disconnect switch component comprises an armature, a contact, a magnet, and a bellow. The armature is connected to the movable contact mounted on the magnet. The bellows is mounted at the center of the switch. When a load current passes through the contact, the magnetic force of the magnet causes the armature to move up and down, thus activating the contact and creating an open circuit.

The ER12-100N3PR is best suited for applications such as transformers, generators, busbar systems, and emergency power systems. It is designed to provide reliable switching operation with minimal arcing, making it ideal for applications where short-term interruptions of service are likely to occur.

The ER12-100N3PR disconnect switch component is an essential piece of electrical equipment for many applications, providing an efficient and reliable way of disconnecting electrical loads when needed. By using a reliable and proven design, the component ensures reliable and consistent performance under any conditions. It is the ideal solution for a variety of applications where reliability and safety are paramount.
