Legrand DMX³ 2500 Open Circuit Breakers and DMX³-I 2500 Open Switches

This document provides comprehensive technical information for the Legrand DMX³ 2500 series of open circuit breakers and DMX³-I 2500 series of open switches. These devices are designed for optimal protection in electrical installations up to 6300 A, offering robust electrical and mechanical performance, high breaking capacity, and extensive accessory options.

1. Utilization

The DMX³ open circuit breakers offer optimal solutions for protection at the origin of low-voltage electrical installations (IEC/EN 60364-1) up to 6300 A. Their electrical and mechanical robustness, breaking capacity, and accessory possibilities make them well-suited for these requirements. The DMX³ range also includes the DMX³-I range of switches without trip units, offering high performance in terms of insulation, robustness, closing, and withstand capacity. Both ranges are designed to enhance service continuity, considering energy efficiency and environmental aspects.

2. Range

The DMX³ 2500 series includes fixed and withdrawable versions with UP MP2.10 and MP4.10 protection units, available in 50 kA, 65 kA, and 100 kA breaking capacities.
