ER12-25N6SR

Disconnect Switch Components

ER12-25N6SR is a disconnect switch component usually used in medium-voltage applications typical up to 38kV. It is a device that provides full circuit isolation, allowing workers to safely work on electrical systems. In order to ensure safety to the operators, the disconnect switch must securely isolate the equipment and system for any manner of power up testing, inspection, maintenance, and other operations of the system.

Application Field of ER12-25N6SR

The ER12-25N6SR disconnect switch component is suitable for both indoor and outdoor environments and is widely used in many applications, including home lighting, residential and commercial distribution, industrial and commercial power systems, transmission systems, distribution systems and industrial automation. It is an ideal solution for a wide range of applications, from low voltage distribution to medium voltage applications.

The ER12-25N6SR disconnect switch component is suitable for both single-phase and three-phase applications. It is available in different types, ranging from a single-pole disconnect switch to a high-amp 4-pole switch with a rated current of up to 6300A. The switches are engineered to offer a safe and reliable operation. They are constructed with a robust insulated plastic housing which increases the component’s durability, safety, and overall performance. It is UL rated to 458 and CSA certified.

Working Principle of ER12-25N6SR

When the disconnect switch is closed, the electricity flows normally and the equipment works. When it is opened, the electricity is interrupted and the equipment will not be supplied with power. The ER12-25N6SR disconnect switch component features a unique operating mechanism which allows for an easy and secure opening and closing of the switch. It has three position settings: closed, open and testing.

When the switch is in the closed position, the current flows through the contacts and the circuit is completed. When the switch is open, the electricity is interrupted and the circuit is broken. When in the testing position, the switch provides power only when a voltage is detected and opens when the voltage is removed. This feature allows the switch to be tested before it is operated.

The ER12-25N6SR disconnect switch component is also equipped with an overload protection system. The system protects the switch from overvoltage and overcurrent which could cause damage to the switch and the electrical system. The disconnect switch also meets all safety standards and is tested to ensure it works properly.

With its versatile features, the ER12-25N6SR disconnect switch component is an ideal solution for a wide range of applications. Its reliable operation, robust construction and overload protection systems make it an excellent choice for medium-voltage applications.
