Power switch with thermal-magnetic trip unit with built-in residual current device DPX3 250 4P R-PR 200A 25kA 420228

Power breaker – reliable protection for your installation

This four-pole DPX3 250 power breaker from Legrand guarantees safety and effective protection in your circuit. Designed to protect electrical installations against overloads and short circuits, it is perfect for both residential and commercial buildings. The built-in Residual Current Device (RCD) further increases safety by protecting against electric shock.

Functionality and parameters

The breaker is characterized by a high rated current of 200A and a short-circuit breaking capacity of 25kA at 400V. The setting range of the overload release is from 160 to 200A, allowing for precise adjustment to the specifics of the protected circuit. The integrated undervoltage release provides an additional layer of protection, and the presence of auxiliary contacts (1 normally open and 1 changeover) allows for connection of breaker status signaling or remote control. Mounting on a TH rail is simple and intuitive, making installation and servicing easier.

• High current rating: 200A – ideal for circuits with high power demand.
• Short-circuit breaking capacity: 25kA – effectively interrupts a short circuit, minimizing the risk of damage.
• Built-in RCD protection: increases safety by protecting against electric shock.
• Wide adjustment range: allows precise adjustment to the load characteristics.
• TH rail mounting: ensures quick and easy installation.
• Auxiliary contacts: allow integration with signaling and control systems.
• Solid construction: guarantees long-lasting and reliable operation.

Design and application

The DPX3 250 breaker is designed for durability and reliability. Its solid housing made of high-quality materials provides resistance to mechanical damage and environmental conditions (IP30 protection). Screw connection of the main contacts guarantees a secure and stable connection of the wires. The device is designed for permanent installation, ensuring its stability during use. Thanks to the universal rated voltage range (220…690V), it can be used in various types of electrical installations. Additionally, the possibility of mounting an optional motor drive expands the functionality of the breaker, enabling remote control.
