Isolating switch Dumeco 4P 400A DMV-400N/4 1814413

Disconnect switch – reliable power disconnection

The Eaton DMV-400N/4 disconnect switch is a robust and safe solution for isolating electrical circuits. Designed to operate at voltages up to 690V and currents of 400A, it provides effective protection of the installation against overload and short circuit. Its compact design and high-quality workmanship make it an ideal choice for both professional installers and end users.

Functionality and application

The device is used to safely disconnect the load in electrical installations, allowing maintenance or repair work to be carried out without the risk of electric shock. Thanks to the visible isolation gap, it provides visual certainty that the circuit is completely disconnected. It can be used in switchboards, control cabinets and other industrial and construction applications. Its versatility makes it suitable for many different types of installations.
