Disconnect switch DPX-IS 250 3P 100 A front trigger 026631

Isolator switch – reliable installation protection

The DPX-IS 250 isolator switch is a three-pole device designed for safely disconnecting electrical circuits. A rated continuous current of 100 A makes it ideal for use in commercial and industrial buildings, as well as in more demanding home installations. The design with a front trigger ensures convenient operation and quick identification of the device status.

Functionality and application

This isolator switch is not only a protective element, but also an important element of the electrical infrastructure. It allows for safe disconnection of the load during maintenance or repair work. Thanks to the possibility of cooperation with overvoltage and undervoltage releases (releases available separately), it can be adapted to the specific needs of the installation, providing additional protection against network irregularities. The possibility of mounting on a TH35 bracket and in switchboards facilitates integration with the existing infrastructure.

Key features and benefits

• High resistance to short-circuit currents: Rated conditional short-circuit current Iq at 100 kA and withstand short-circuit current Icw 9 kA guarantee effective protection against the effects of overloads and short circuits.
• Versatility: The ability to cooperate with various types of releases (overvoltage, undervoltage) and auxiliary contacts allows you to adapt the isolator to individual installation requirements.
• Safety of use: The locking mechanism prevents accidental switching on of the device, and a clear marking of the contact positions ensures easy identification of the circuit status.
• Durable construction: Made of high-quality materials and compliant with IEC/EN 60947-3 standard ensure long-lasting and reliable operation of the device.
• Easy installation: Designed for mounting on a TH35 bracket and in switchboards, which facilitates installation and integration with existing electrical infrastructure.
• Wide range of operating voltages: Rated operating voltage from 230 V to 690 V allows for use in various electrical installations.
• Main and safety switch function: Meets the requirements for main and safety switches, which increases the functionality of the device.
• Equipped with 3 switchable auxiliary contacts: Allows integration with control and signaling systems.
• Screw connection used: Ensures a secure and durable connection of the wires.

This isolator is a solid solution for professionals and users looking for reliable protection of their electrical installations.
