Power circuit breaker with thermal-magnetic trip unit DPX3 250 4P 160A 25kA 420217

Robust protection for electrical installations – DPX3 250 4P 160A circuit breaker

This four-pole power circuit breaker with a thermomagnetic release DPX3 250 with a rated current of 160A and a short-circuit breaking capacity of 25kA guarantees safety and reliability in your installation. Designed for both domestic and industrial applications, it provides effective protection against overloads and short circuits. Manufactured by the renowned Legrand, it meets the highest quality standards.

Functionality and installation

The DPX3 250 circuit breaker is characterized by its universal mounting – it can be easily installed on a TH rail. Its design, intended for permanent mounting, ensures stability and long-term operation. Connection of the main circuits is done using screw connections, which facilitates and speeds up the installation process. Additionally, the presence of a trip indicator allows for quick identification of the device status.

Characteristics and parameters

The thermomagnetic release in the range of 128-160A provides precise protection against overloads, and the setting range of the short-circuit release (800-1600A) guarantees a quick response in the event of a short circuit. The rated continuous current at 160A allows for safe loading of the installation. The built-in undervoltage release increases the functionality of the device, and the option of mounting a motor drive expands its application possibilities. Equipped with one changeover auxiliary contact and one normally open and one normally closed contact, it enables integration with control and signaling systems. The IP30 degree of protection provides protection against contact and the ingress of solid objects. The short-circuit capacity of 25kA at 400V/50Hz confirms its high effectiveness in emergency situations.
