Power switch with electronic trip unit with built-in residual current device with measurement functions DPX3 250EL+P+BL.R 4P 160A 70kA 420688

DPX³ 250EL+P+BL.R circuit breaker is an advanced device that combines the functions of a power circuit breaker with an electronic trip unit, residual current device (RCD), and measurement capabilities. It is a comprehensive solution for protecting electrical installations, ensuring safety and reliable operation. Designed for mounting on a TH35 rail, it can be used in industrial, commercial installations, and residential buildings with increased requirements.

Protection and functionality in one device

This four-pole (4P) circuit breaker with a rated current of 160A and a short-circuit breaking capacity of 70kA at 400V provides effective protection against overloads, short circuits, and leakage currents. The built-in RCD with adjustable tripping current (0.03 - 0.3 - 1 - 3 A) and time delay (0 - 0.3 - 1 - 3s) minimizes the risk of electric shock and equipment damage. The electronic trip unit allows for precise adjustment of the operating characteristics to the specifics of the protected circuit.

Flexibility and ease of installation

The DPX³ 250EL+P+BL.R circuit breaker is characterized by its versatility thanks to the possibility of mounting on a TH rail or directly on a mounting plate. Cable connection is made using screw connections, ensuring a secure and durable connection. Additionally, the ability to connect a motor drive expands the functionality of the device, enabling remote control. The trip indicator informs about the operation of the protection, facilitating the location and removal of faults.

Adaptation to installation needs

The setting range of the overload trip unit (64…160A) and the short-circuit trip unit (96…1600A) allows for precise adjustment of the circuit breaker's operating parameters to the characteristics of the load. The integrated undervoltage release further increases the safety of the installation, protecting against the effects of voltage drops. This makes the device ideal for both installers looking for flexible solutions and end-users who value reliability and safety.
