Power switch with electronic trip unit with built-in residual current device DPX3 250 EL+BL.R 4P 100A 70KA 420657

Power circuit breaker with residual current protection – reliable installation protection

This four-pole DPX3 250 EL+BL.R power circuit breaker with a rated current of 100A and a short-circuit breaking capacity of 70kA is a solid solution for protecting electrical circuits. Equipped with an electronic trip unit and a built-in residual current device, it provides comprehensive protection against overloads, short circuits and electric shock. It will be suitable for both industrial and commercial installations where high reliability and safety are required.

Functionality and application

The circuit breaker is designed for mounting on a TH35 rail, which facilitates its installation and replacement. Screw connection of wires ensures a secure electrical connection. The built-in undervoltage release further increases the safety of the installation, protecting it from the effects of voltage drops. Thanks to the integrated short-circuit to ground protection, the circuit breaker effectively minimizes the risk of electric shock. It also has a trip indicator that informs about the operation of the protection.

Advantages for the installer and end user

• Versatility: Adjustable overload (40-100A) and short-circuit (60-1000A) trip settings allow you to adapt the circuit breaker characteristics to the specifics of the protected circuit.
• Safety: Built-in residual current device and undervoltage release provide comprehensive protection against various electrical hazards.
• Easy installation: The design adapted for mounting on a TH35 rail significantly speeds up the installation process.
• Status indication: The trip indicator facilitates identification of the cause of power failure and quick location of the fault.
• Switching capacity: High short-circuit capacity (70kA at 400V) guarantees effective disconnection of the circuit in the event of a serious failure.
• Flexibility: The possibility of connecting a motor drive (optional) expands the functionality of the device, enabling remote control.
• Compatibility: The ability to mount DPX3 auxiliary equipment ensures full integration with other elements of the Legrand system.

The DPX3 250 EL+BL.R circuit breaker is an investment in the safety and reliability of the electrical installation – both for professionals and end users. It provides effective protection against the effects of failures, minimizing the risk of equipment damage and threats to life.
