Isolating switch iSW-40-3 40A 3-pole A9S65340

Insulation disconnect switch – safety and functionality in one

This three-pole iSW-40-3 disconnect switch with a rated current of 40A is a reliable solution for safely disconnecting electrical circuits. Designed for installers and users, it provides effective isolation and control over the installation. Its compact design, occupying 3 modules, facilitates mounting in distribution boards.

Features and application

The iSW-40-3 disconnect switch is designed for the isolation disconnection of circuits and fragments of electrical installations. It meets safety standards, guaranteeing full protection against accidental contact with live conductors after disconnection. The high breaking capacity of 5kA provides resistance to overloads and short circuits. Additionally, the possibility of equipping it with a door drive, auxiliary contact or plug-in base increases its functionality and adapts it to the specific needs of the installation.

• Safety first: The built-in Visi-Safe indicator visually confirms the open state of the contacts, eliminating the risk of incorrect assessment of the insulation status. This is crucial for safety during maintenance and repairs.
• Versatility: Suitable for use in AC installations with a rated voltage of 240V and a minimum of 415V.
• Compact dimensions: A width of 3 modules allows for efficient use of space in the distribution board (installation depth 75.5 mm).
• Durability: The rated breaking capacity at 5kA guarantees reliable operation even in difficult working conditions. Short-circuit strength (Icw) is 1.26 kA.
• Protection class IP20: Provides protection against finger contact, which is important for safe use.
• Forced separation: Compliance with DIN VDE 0113 ensures complete galvanic isolation after disconnection of the circuit.

This disconnect switch is not only a safety element, but also a convenient tool for installers, enabling quick and safe installation and easy adaptation to individual customer needs. Thanks to the possibility of expanding with additional functions, it is a flexible solution for various applications in residential, commercial and industrial construction.
