Power switch with thermal-magnetic trip unit with built-in residual current device DPX3 160+BL.R 4P 125A 16kA 420036

Power switch with protection – reliable installation protection

This four-pole DPX3 160 power switch, with a rated current of 125A and a short-circuit breaking capacity of 16kA, is a solid solution for protecting electrical circuits. Designed for use in both industrial and commercial buildings, it provides effective protection against overloads and short circuits. The built-in residual current device (RCD) further enhances safety.

Functionality and application

This switch, mounted on a TH rail, is designed to protect circuits with a rated voltage of up to 690V. Its construction based on a thermal-magnetic trip unit guarantees a quick and precise response to irregularities in the circuit. This minimizes the risk of damage to equipment and fires. The overload trip unit with an adjustment range of 100-125A allows you to adjust the sensitivity to the specific needs of the installation. An additional normally open and changeover auxiliary contact allows connection of a switch status indicator or remote control.

Advantages for the installer and user

• Versatility: Possibility of mounting on a TH rail and optional motor drive facilitate installation and integration with existing systems.
• Safety: Integrated earth fault protection and undervoltage release provide comprehensive protection of the installation and equipment.
• Precision: A wide adjustment range of the overload trip unit allows precise adaptation to the load characteristics.
• Status indication: The trip indicator informs about the operation of the protection, making it easier to locate the problem.
• Solid construction: Made of high-quality materials, it guarantees durability and reliable operation in harsh working conditions (IP30 protection).
• Easy connection: Screw connection of the main contacts ensures a secure and durable connection of the wires.
• Expandability: Optional motor drive allows remote control of the switch, which is particularly useful in automated systems.

Using this switch is not only meeting safety requirements, but also an investment in the long-term and trouble-free operation of the entire electrical installation.
