— Distinctive features
The evolution of SACE Emax 2 from circuit breaker to Power Manager continues, embedding more and more functionalities to become the all-in-one solution to help manage "low-voltage distribution systems".
Performance The SACE Emax 2 range is made up of 4 sizes: E1.2, E2.2, E4.2 and E6.2 up to 6000A, which enable switchgear of compact dimensions and high rat- ings to be built with busbars of reduced length and cross-section. The protection trip units, auxiliary connections and main accessories are the same throughout the range to simplify design and installation. Furthermore, the sizes from E2.2 to E6.2 have the same height and depth. The rating levels are updated and standardized throughout the sizes to meet the demands and needs of today’s installations, from 42kA to 150kA, and to standardize switchgear projects. High short-time currents, together with the effi- ciency of the protection functions, to provide com- plete selectivity in all situations. Accurate design and choice of materials enable op- timization of the overall dimensions of the circuit breaker. In this way switchgear of compact dimen- sions can be built to help deliver outstanding sav- ings at the same performance.
Furthermore it can be ordered with a triple marking label, IEC, UL and CCC. SACE Emax 2 air circuit breakers are certified for Class 1 active energy measurement in compliance with the IEC61557-12 standard. This permits it to satisfy highly demanding requirements of energy efficiency and to perfectly fit into SCADA systems thanks to a current detection proximal to 0. Achieving maximum efficiency of an electrical in- stallation requires intelligent management of power supplies and energy use. For this reason, the new technologies used in SACE Emax 2 circuit breakers allow the productivity and reliability of in- stallations to be optimized, and at the same time, power consumption to be reduced while fully re- specting the environment. New advanced functionalities, together with Pro- tection trip units and Communication and system devices contribute to make SACE Emax 2 the circuit breaker that maximizes efficiency in all low-voltage electrical installation.
