Integrated measurement: choosing a more compact solution 8

DPX³ units with integrated measurement combine an electronic circuit breaker and a high-performance measurement control unit with LCD display in a single device. Integrated measurement means: Protection of the installation against electrical faults Measurement and display of the installation’s parameters Time-saving as a result of simplified installation and wiring Space-saving in the enclosure CONVENTIONAL SOLUTION Legrand also has a complete range of meters, measurement control units and current transformers for installations equipped with devices without integrated measurement....

Total selectivity for optimum continuity of service 10

Selectivity between Legrand circuit breakers, which ensures continuity of service, is optimised by the improved performance of the DPX³ devices. In critical configurations, the dynamic and logical selectivity offered by the new electronic DPX³ protection units provide total selectivity in all situations. LOGICAL SELECTIVITY This is “smart” selectivity, obtained by means of communication between DPX³ (and/or DMX³) electronic circuit breakers that are connected together via an external wired link. It enables there to be total selectivity between several levels, as well as a reduction of the...
