Power switch with electronic trip unit with built-in residual current device with measurement functions DPX3 250EL+P+BL.R 4P 100A 50kA 420485

Advanced protection and measurement in one device

The DPX3 250EL+P+BL power switch is a comprehensive solution for demanding electrical installations. It combines the functions of an overcurrent switch, a residual current device (RCD) and an advanced measurement module, providing not only effective protection but also access to key parameters of the installation operation. Designed for mounting on a TH rail, it is ideal for both professionals and end-users looking for a reliable and functional solution.

Functionality and safety

This four-pole (4P) switch with a rated current of 100A and a breaking capacity of 50kA at 400V guarantees a quick and effective response in case of overloads and short circuits. The built-in residual current protection protects against electric shock, and the electronic release ensures precise adjustment of the characteristics to the specifics of the load. In addition, the integrated measurement module with an LCD screen allows monitoring of currents, voltages, frequency, power and energy – which is particularly valuable in installations requiring energy consumption optimization.

Comfort of installation and use

The design adapted for mounting on a TH rail facilitates installation and replacement of the device. Screw connection ensures secure and durable wire connections. The switch also has a trip indicator, which makes it easier to identify the cause of the operation. The possibility of connecting a motor drive (optional) increases comfort of operation in hard-to-reach places. The adjustable setting range of the overload release (40…100A) and short-circuit release (60…1000A) allows for precise adaptation to the needs of a specific installation. Additionally, the presence of auxiliary contacts (normally closed: 0, changeover: 1, normally open: 1) expands the possibilities of integration with control and signaling systems.
