A great many industries, from commercial and residential buildings to engineering plants, rely on reliable current flows to keep their operations running efficiently. Disconnect switches are essential components in this process. Specifically, the ER4-40N6SR Disconnect Switch, which is widely used in multi-voltage heavy duty current control applications, is one of the most reliable solutions in its class.

The ER4-40N6SR is a high power ratings disconnect switch with a thermal contact rating of 10,000 A. It is suitable for operations with voltages up to 600 volts and currents up to 10,000 amperes. It features an independent parallel control system that allows for simultaneous operation of both loads and disconnects. The switch also has an inescapable toggle lever with a lockable switch lid and panel-fitted mounting holes that ensure secure installation.

The ER4-40N6SR is designed to provide superior performance and reliability. It is designed with protective features such as a lockable switch lid, which prevents unauthorized operation. Additionally, it features a thermal overload switch, which will shut off the current automatically in the event of an overload. The switch also includes an internal arrester, which eliminates dangerous electrical surges from entering the system.

The ER4-40N6SR disconnect switch has a wide range of applications. It is commonly used in residential and commercial buildings, industrial plants, and marine vessels. In addition, the switch is also suitable for various applications in the automotive and aerospace industries. It is also used in electrical transformer labs, HV testing facilities, and oil and gas platforms.

The ER4-40N6SR Disconnect Switch is based on a simple but effective working principle. When the switch is in the ON position, the electrical current flows through the system. When the switch is in the OFF position, the switch isolates the contact and no current is allowed to pass through. When the switch is locked in the OFF position, it prevents any unauthorized use. This ensures that the system remains safe and secure at all times.

In summary, the ER4-40N6SR Disconnect Switch is an essential component in multi-voltage heavy duty current applications. It is designed with a thermal contact rating of 10,000 A and is suitable for voltage up to 600 volts and currents up to 10,000 amperes. It features a lockable switch lid and panel-mounted mounting holes for secure installation. Additionally, it provides superior performance and reliability with a thermal overload switch and internal arrester to ensure safety of the system. This switch is widely used in residential and commercial buildings and industrial applications.
