Power disconnect switch – reliable installation protection

The 3-pole 400A BG3 N3-400 power disconnect switch is a key element of any electrical installation, providing safe and effective circuit disconnection. The device, manufactured by the renowned Eaton company, is characterized by high reliability and durability, making it an ideal solution for both professional installers and end users. The design of the disconnect switch allows for mounting in distribution boards, as well as indirect mounting on a plate.

Functionality and application

This disconnect switch serves as a main disconnect switch and a maintenance disconnect switch. This allows for safe disconnection of power during maintenance or modernization work. Additionally, it can function as an emergency switch, providing quick disconnection of the circuit in the event of a dangerous situation. The rated continuous current of 400A and the high short-circuit withstand capacity (12 kA) guarantee effective protection against overloads and short circuits. The possibility of using an optional voltage release allows for additional adjustment of the operating parameters to the specific requirements of the installation.

Construction and characteristic features

The BG3 N3-400 disconnect switch is distinguished by a solid construction of a permanently mounted device. It has three poles and a lever for convenient operation. Connection of the main contacts is made using a screw connection, which ensures a secure and durable electrical connection. The locking mechanism increases safety of use, preventing accidental switching on or off of the disconnect switch. Compact dimensions (140 mm width, 275 mm height and 159 mm depth) facilitate mounting even in limited spaces. The IP20 degree of protection provides basic protection against touching live parts.

Worth knowing: Accessories from the LZM/LN and NZM/N series are mutually compatible, allowing for flexible adaptation of the disconnect switch to specific installation needs. A wide selection of additional accessories – remote drives, releases, auxiliary contacts – increases the functionality of the device and allows its integration with automation and signaling systems.
