Main isolating disconnect switch IS-20/1 276258

Isolator switch – reliable power disconnection

This single-pole isolator switch IS-20/1 from Eaton is designed for safely disconnecting electrical circuits. It is suitable for both home and commercial installations where reliable operation and high resistance to working conditions are required. The device's construction provides effective insulation, which is crucial for safety during maintenance or repairs.

Functionality and application

The IS-20/1 isolator switch with a rated current of 20A and a voltage of 240V is primarily used as a main switch in distribution boards. Its compact size – only 1 module wide – allows for easy installation even in limited spaces. The “arrow” symbol on the housing facilitates visual identification of the switch status – whether the circuit is on or off. The IP40 protection class provides protection against contact and ingress of solid objects, increasing safety.

Key features and benefits

• High short-circuit strength: Rated switching capacity of 12.5 kA and short-circuit current rating (Icw) of 1 kA guarantee reliable operation even in the event of overloads or short circuits in the installation.
• Durable construction: High contact wear resistance translates to a long device life and minimizes the risk of failure.
• Wide range of conductors: The ability to connect conductors with a cross-section of up to 50mm2 facilitates integration with various types of electrical installations.
• Contact position indicator: Allows for unambiguous visual control of the switch status, increasing work safety.
• Snap-action operation: Ensures quick and reliable circuit switching.
• Compact dimensions: 1 module width makes it easy to install in tight distribution boards.
