Main isolating disconnect switch IS-20/3 276260

Main isolating switch IS-20/3 is a three-pole device designed for safely disconnecting electrical circuits. It finds application in both domestic and industrial installations where reliable isolation and the ability to manually switch off the power are required. Its modular design (3 modules) facilitates mounting in distribution boards.

Features and application

The device is characterized by a rated current of 20A and a rated voltage of 415V, making it suitable for protecting circuits with medium power. Short-circuit strength at 1 kA and breaking capacity of 12.5 kA provide effective protection against the effects of short circuits and overloads. The "arrow" symbol on the housing facilitates visual identification of the device status - on or off. The IP40 degree of protection guarantees protection against the ingress of solid objects larger than 1mm, which is important in environments with increased dust.

Advantages for installers and users

• Safety: Provides complete circuit isolation after switching off, which is crucial during maintenance and service work.
• Durability: High contact wear resistance translates into long life and reliable device operation.
• Versatility: The ability to connect wires with a cross-section of up to 50mm2 provides flexibility in choosing wires adapted to a specific application.
• Contact position indicator: Allows quick and reliable verification of the device status - whether the contacts are closed or open.
• Easy installation: Modular design facilitates installation in standard distribution boards.
• Incremental switching: Ensures smooth and controlled circuit switching, minimizing the risk of damage to connected devices.

This switch is a solid solution for anyone who values safety, reliability and ease of use. It is an ideal choice for both professional installers and end users looking for a proven element for their electrical installation.
