Disconnect switch components are practical and versatile elements for any industrial application. They are mostly used on high voltage circuits and serve as both a protection and control element. The ER12-1200N3PR series from Cooner Wire, is a medium voltage disconnect switch that provides good protection to the equipment, control circuits and switchgear. This series of disconnect switches can be used for 600V or less, and can operate under loads exceeding 1000A.

The ER12-1200N3PR is designed and manufactured to comply with ANSI C37.20 and UL 489 standards. The durable construction ensures reliable performance in various environments. It is constructed of poles and copper contacts with either porcelain or epoxy insulators. The contact material is rated for a maximum voltage of 1200V, allowing for safe operation in applications requiring high levels of isolation and protection.

This series of disconnect switches has a four-polar design, which provides a pair of poles for each of the live lines and also controls two contact blocks. The contacts blocks are connected to the coil, which is powered by the voltage supplied, and its role is to open and close the switch when needed. This switching mechanism is simple yet effective and provides an efficient and reliable connection and disconnection.

The ER12-1200N3PR disconnect switch is mainly used in applications where medium voltage is needed. It is suitable for use in commercial and industrial lighting, as well as for controlling electrical devices such as air conditioners and refrigerators. It is also suitable for controlling high voltage equipment, such as transformers and circuit breakers. This series of disconnect switches is designed to provide a long-term, reliable and efficient connection and disconnection in applications where power control and automation are required.

The ER12-1200N3PR disconnect switch is designed with safety in mind. It is equipped with features such as overcurrent protections, differential current protection, and self-supervision systems. This helps to provide maximum protection for operators and reduce the risk of equipment damage. The disconnect switch also comes with shock-proof plastic covers to ensure that the user does not get in contact with the electrical components and it is also IP65 rated for weatherproof operation.

The ER12-1200N3PR disconnect switch is a practical and reliable solution for medium voltage applications and it is the perfect choice for providing a secure connection and disconnection in applications where safety is paramount. Its simple four-pole design and easy to install and maintain system make it an ideal choice for industrial or residential applications.
