Isolating switch Dumeco 3P 250A DMV-250N/3 1814408

Isolator switch DMV-250N/3 – reliable disconnection with visible break

The Dumeco DMV-250N/3 isolator switch is a three-pole device designed for the safe disconnection of electrical circuits. It is characterized by the presence of a visible isolation gap, which ensures visual certainty of the disconnection status. It is a solid alternative to compact disconnectors, especially in situations where advanced additional functions are not required. The device is distinguished by its shallow mounting depth, which facilitates installation even in limited spaces.

Construction and application

The construction of the isolator is based on a complete device in an enclosure, designed for mounting on a plate. Designed to operate in circuits with a rated voltage of 690 V and a continuous current of 250 A, it is perfect for industrial and commercial installations. The rated conditional short-circuit current at 100 kA guarantees resistance to overloads and short circuits. It can also be used as an emergency switch. The connection of the main contacts is made using screw connections, which ensures a stable and reliable electrical connection.

Key features and benefits

• Visible isolation gap: Provides unambiguous visual verification of the disconnection status, increasing work safety.
• Compact dimensions: Width 205 mm, height 135 mm and depth of only 63 mm make it easy to install in tight spaces.
• High short-circuit resistance: Rated conditional short-circuit current of 100 kA protects the installation against the effects of sudden overvoltages.
• Versatile application: The possibility of using it as an emergency switch expands its scope of use.
• Rated operating power for AC-23, 400 V: At 140 kW, it enables operation of demanding electrical receivers.
• Durable construction: The device made of high-quality materials guarantees long life and reliable operation.
• Rated withstand short-time current Icw: With a value of 12 kA provides additional protection against the effects of short-term overloads.

The Dumeco DMV-250N/3 isolator switch is a solid and reliable solution for professionals and end users looking for a safe and effective way to disconnect electrical circuits. Its compact dimensions and high resistance to working conditions make it an ideal choice for a variety of industrial and commercial applications.
