Main isolating switch IS-25/3 276264

Isolator – safety and reliability in your installation

This three-pole isolator is designed for safely disconnecting electrical circuits. It is suitable for both industrial and public building installations, providing effective isolation and protection against accidental switching on. The device is characterized by a high short-circuit strength of up to 12.5kA, which guarantees its reliable operation even in difficult conditions.

Design and application

The IS-25/3 isolator is designed for indirect mounting in distribution boards. Its compact dimensions (3 modules wide) allow for easy integration with existing infrastructure. Designed to operate at AC voltage up to 690V and rated current of 25A, it enables operation of loads up to 13kW at 400V (AC-23). Equipped with a knob as a switching element, it provides convenient and intuitive operation. An “arrow” symbol on the housing facilitates visual identification of the isolator status.

Advantages and benefits

• High short-circuit strength: The ability to withstand a short circuit of 12.5kA ensures the safety of the installation and minimizes the risk of damage.
• Wide range of conductors: The ability to connect conductors with a cross-section of up to 50mm² facilitates installation and allows adaptation to various needs.
• Contact position indicator: Allows for unambiguous visual control of the isolator status – whether the circuit is open or closed.
• Durable construction: Made of high-quality materials guarantees long-lasting and trouble-free operation of the device.
• Versatility: Can function as a main and service isolator, increasing its functionality.
• Protection class IP40: Provides protection against access to live parts and against the ingress of solid objects larger than 1mm.
• Rated current 25A: Enables safe disconnection of circuits with appropriate current intensity.

The IS-25/3 isolator is a solid and reliable solution for professionals and end-users looking for a safe way to disconnect electrical circuits. Its durability, versatility and ease of installation make it an ideal choice for a wide range of applications.
