Isolating switch Dumeco 3P 400A DMV-400N/3 1814411

Isolator switch – reliable power disconnection

The DMV-400N/3 isolator switch is a solid and safe device designed to disconnect electrical circuits. It provides a visible isolation gap, guaranteeing complete safety during maintenance and repair of installations. It is an alternative to compact disconnectors, especially where no extended additional functions are required. The device is characterized by a compact design and shallow mounting depth, making it easy to install even in limited spaces.

Design and operating parameters

The isolator is designed to operate in installations with a rated voltage of 690 V and a continuous current of 400 A. It withstands a short-circuit current of up to 12 kA, protecting the circuit from the effects of failures. The rated operating power for AC-23 at 400 V is 180 kW. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The connection of the main contacts is made using screw connections, which ensures a secure and stable connection of the wires. The IP20 protection class protects against accidental contact.
