Disconnect switch with possibility to add an actuator/release iSW-NA-100-3N 100A 3-pole/3P A9S70790

Isolator switch – safety and flexibility in one

The iSW-NA-100-3N isolator switch from Schneider Electric is a reliable device designed to isolate electrical circuits. It provides a safe disconnection of power, both in emergency situations and during maintenance work. The device's design allows for later equipping with overload and undervoltage releases, an auxiliary contact or a door drive, which increases its functionality and adapts it to the specific needs of the installation.

Functionality and technical parameters

The device with a rated current of 100A and a voltage of 415V, made in modular technology (4 modules), is used in residential and industrial switchboards. It has 4 poles (3P+N) which makes it an ideal solution for three-phase installations. Short-circuit strength at 1.5kA and switching capacity of 5kA guarantee effective protection of the circuit against the effects of overloads and short circuits. The Visi-Safe indicator visually confirms the open state of the contacts, which increases the safety of work. Protection class IP20 provides protection against accidental contact.

Application and benefits

This isolator is not only a safety element, but also a central point for system expansion. The ability to add overload and undervoltage releases allows for precise response to changes in the circuit, protecting devices from damage caused by voltage fluctuations. This makes the installation more resistant to failures and provides a stable power supply. DIN rail mounting simplifies installation and integration with existing electrical infrastructure. Forced separation according to DIN VDE 0113 standard further increases safety.
