Main isolating disconnect switch IS-40/1 276270

Isolator switch – reliable power disconnection

The IS-40/1 main isolator switch is a single-pole device designed for safely disconnecting electrical circuits. A rated current of 40A and a breaking capacity of 12.5kA guarantee effective protection of the installation against overloads and short circuits. The device's construction, compliant with IEC/EN 60947-3, ensures high reliability and durability.

Functionality and application

The device finds application in electrical installations of residential, commercial and industrial buildings. Its compact dimensions (1 module width, installation depth of 69.5 mm) allow for easy mounting in switchboards. The "arrow" symbol on the knob facilitates visual identification of the device's status – on or off. A terminal cross-section of up to 50mm² allows connection of large-diameter conductors, which is particularly important in applications requiring high current throughput. Additionally, the isolator switch is compatible with busbars with Xpole protective devices using a jaw terminal with standard fork busbar connection.

Key features and benefits

• High short-circuit strength: Breaking capacity of 12.5kA ensures installation safety even in the event of strong surges.
• Wide range of conductors: The ability to connect conductors with a cross-section of up to 50mm² simplifies installation and provides flexibility in conductor selection.
• Durable construction: Snap-action switching and high contact wear resistance guarantee a long device life and minimize the risk of failure.
• Safety of use: IP40 protection rating protects against accidental contact and the ingress of solid objects larger than 1mm, increasing work safety.
• Compact dimensions: A width of only 1 module allows for efficient use of space in the switchboard.
• Clear status identification: The "arrow" symbol on the knob facilitates quick assessment of the device's status (on/off).
• Compliance with standards: Meets the requirements of IEC/EN 60947-3, confirming its safety and reliability.

The IS-40/1 isolator switch is a solid and reliable solution for professionals and end-users who value the safety and durability of their electrical installation.
