Power switch with electronic trip unit with built-in residual current device DPX3 250 EL+BL.R 4P 160A 70KA 420658

Residual Current Device (RCD) – reliable protection for your installation

This four-pole DPX3 250 EL+BL.R circuit breaker with a rated current of 160A and a short-circuit breaking capacity of 70kA is a solid solution for protecting electrical circuits. The use of an electronic trip unit combined with a built-in residual current device provides comprehensive protection against overloads, short circuits and electric shock.

Functionality and application

This circuit breaker is used in electrical installations in commercial, industrial and residential buildings where high reliability and effective protection are required. It is designed to protect circuits powering various types of receivers, including devices with high power consumption. The built-in undervoltage release further increases the safety of the installation, protecting against the effects of voltage drops. The ability to mount additional modules allows you to expand the functionality of the circuit breaker, adapting it to the specific needs of the installation.

Key features and benefits

• High short-circuit breaking capacity (70kA): ensures effective protection of the installation even with high short-circuit currents.

• Built-in residual current device: minimizes the risk of electric shock and prevents fires caused by ground faults.

• Electronic trip unit: precise and fast response to overloads and short circuits, which translates into a longer lifespan of devices.

• Adjustable overload trip unit setting range (64…160A): allows you to match the circuit breaker characteristics to the specifics of the protected circuit.

• TH rail mounting: simplifies and speeds up installation and ensures stable mounting.

• Expandability: compatibility with DPX3 accessories allows you to adapt the functionality to individual needs.

• Screw terminals: provide a secure and durable connection of conductors with a cross-section of up to 150mm².

• Trip indicator: makes it easier to identify the status of the circuit breaker and locate faults.

Design and operating parameters

The DPX3 250 EL+BL.R circuit breaker is characterized by a solid design intended for operation in difficult conditions. The IP30 degree of protection provides protection against contact and ingress of solid objects. The device is adapted to operate in the range of rated voltages from 220 to 690V, which makes it a universal solution for various types of electrical installations. The setting range of the delayed short-circuit trip is from 96 to 1600A, allowing for precise adjustment to the load characteristics. It has one changeover auxiliary contact and two normally open auxiliary contacts, providing the possibility of connecting a circuit breaker status indicator or controlling other devices.
