Isolator switch iSW-100-3 100A 3-pole A9S65391

Isolator switch for safe disconnection of circuits

The iSW-100-3 isolator switch, catalog number A9S65391, is a reliable device designed for the isolation of electrical circuits and their sections. The 3-pole (three-pole) design allows for effective disconnection of the power supply, ensuring safety during maintenance and service work. The device is particularly useful in industrial installations and commercial buildings where high reliability and safety are required.

Functionality and technical parameters

The switch is characterized by a rated current of 100A and a rated voltage of 240V (minimum 415V). The rated switching capacity is 5kA, and the short-circuit strength (Icw) is 1.5kA – these parameters guarantee effective protection against overloads and short circuits. The compact design of the device, taking up 3 modules in width, facilitates mounting in electrical switchboards. The IP20 degree of protection provides basic protection against contact and ingress of solid objects.

Safety and additional functions

A key feature of the switch is the Visi-Safe indicator, which visually confirms the opening of the contacts, giving certainty of complete circuit isolation. In addition, the switch can be equipped with a door drive or an auxiliary contact, which increases its functionality and adapts it to the specific needs of the installation. The possibility of mounting a base plug facilitates quick and convenient connection of the device. Compliance with DIN VDE 0113 standard ensures forced separation, increasing the safety level of the installation.

Mounting and application

The switch is mounted on a DIN rail, which is standard in electrical installations. The device finds application wherever safe and reliable disconnection of electrical circuits is required – from home installations to industrial plants. Thanks to its design and technical parameters, the iSW-100-3 switch is an optimal solution for professionals and end-users looking for high quality and safety.
