Disconnect Switch Components are widely used in many applications. One such component is the ER3R-40N6SB. This is a manual action isolator switch. An isolator switch is used to open and close an electrical circuit. It works by using a lever or handle to operate the switch to break and make the connection respectively.

The ER3R-40N6SB is a universal three phase unit. This means it is suitable for electrical installations operating at AC 3 phase systems of 400 volts or less. It is approved to EN60947-3 standards and can also be used in emergency wind up power supplies. It can be mounted on a single pole mounting box which makes installation simple and efficient.

The ER3R-40N6SB is capable of switching a wide range of currents including those of a 3 phase circuit. The switch is available in two versions; one with a rated current of 40 amps and the other with a rated current of 63 amps. This makes it suitable for the majority of application fields. As it is an isolator, it can be used in many applications including after a generator, an electric motor, an electric panel and any other application that requires isolation of the power supply.

The working principle of the ER3R-40N6SB is relatively simple. It works by using a lever on the side or top of the unit. This lever is used to open and close the contact points inside the unit. By pushing the lever to one side, the contact points will open, thus isolating the electrical current. When the lever is returned to the central position, the contact points will be closed and the supply to the circuit will be enabled.

The ER3R-40N6SB has a long operational life of up to 1,500,000 operations. This is a clear indication of its durability and reliability. It is also tested to IP65 standards and is thus resistant to dust and water ingress. This makes it suitable for both indoor and outdoor applications.

In summary, the ER3R-40N6SB is a well-designed and versatile manual action isolator switch. Its universal three phase design means it is suitable for a wide range of application fields. The lever along with its long operational life combined with its dust and water protection makes it an ideal choice for any area with hazardous conditions. The working principle is simple and straightforward and its ease of installation due to the single pole mounting bracket makes it an efficient choice.
