Power switch with thermal-magnetic trip unit DPX3 250 3P 200A 36kA 420238

DPX3 Power Circuit Breakers – Reliable Protection for Your Installation

The DPX3 250 power circuit breaker is an advanced solution from Legrand, designed to protect electrical circuits in residential, commercial, and industrial buildings. This three-pole circuit breaker with a rated current of 200A and a short-circuit breaking capacity of 36kA provides effective protection against overloads and short circuits, guaranteeing safety and minimizing the risk of failure.

This model is equipped with a thermomagnetic trip unit with an adjustable setting range from 160A to 200A, allowing for precise adjustment to the specific needs of the installation. Additionally, it has a built-in undervoltage release, increasing the level of protection. Mounting on a TH rail simplifies installation and integration with the existing electrical system.

Construction and functionality

The DPX3 250 circuit breaker is characterized by a solid construction of a fixed device. It provides reliable operation in a wide range of rated voltages (220-690V) and meets safety standards (IP30). Screw connection of the main contacts guarantees a secure and durable connection of the conductors. The trip indicator informs about the operation of the protection, facilitating the diagnosis of any problems. The possibility of mounting additional auxiliary contacts and a motor drive expands the functionality of the device, adapting it to more complex applications.

• High short-circuit breaking capacity (36kA): Ensures a quick and effective response in the event of a short circuit, minimizing damage to the installation and equipment.
• Adjustable thermomagnetic trip unit (160-200A): Allows precise adjustment to the load characteristics, protecting against overloads and ensuring stable operation of the installation.
• Built-in undervoltage release: An additional layer of protection against voltage drops that can damage sensitive equipment.
• TH rail mounting: Quick and easy mounting in standard electrical panels.
• Expandability: Compatibility with additional auxiliary contacts and motor drives increases application flexibility.
• Durable construction: The device made of high-quality materials ensures a long service life and reliable operation even in difficult conditions.

DPX3 250 is not only a protective element, but also an investment in the safety and stability of your electrical installation. It is an ideal choice for both professional installers and end-users looking for a reliable solution to protect their homes and businesses.
