New Sace Emax 2 from circuit-breaker to to Power Manager

SACE Emax 2 is a new series of low voltage air circuit-breakers available

up to 6300 A and with the ability to efficiently and simply control electrical

installations – from the traditional to the more complex – with minimum

impact, the new SACE Emax 2 circuit-breakers represent the evolution of a

circuit-breaker into a Power Manager.

Efficiency

SACE Emax 2 air circuit-breakers have been designed to manage, with maximum efficiency, all low voltage electrical

installations: from industrial plants, naval applications, traditional and renewable power generation installations to buildings,

shopping centres, data centres and communication networks.

Achieving maximum efficiency of an electrical installation in order to reduce consumption and waste requires intelligent

management of power supplies and energy use. For this reason, the new technologies used in the SACE Emax 2 circuitbreakers

allow the productivity and reliability of installations to be optimized, and at the same time, power consumption to be

reduced while fully respecting the environment.

Control

The exclusive Power Controller function available on the new SACE Emax 2 circuit-breakers monitors the power managed

by the circuit-breaker, keeping it below the limit set by the user. As a result of this more effective use, the peak of power

consumed can be limited allowing savings on electricity bills.

The Power Controller, patented by ABB, disconnects non-priority utilities, such as electric car charging stations, lighting or

refrigeration units, during the times when consumption limits need to be respected, and connects them again as soon as it is

appropriate. When required, it automatically activates auxiliary power supplies such as generator sets. No monitoring system

is required: it is sufficient to set the required load limit on Emax 2, which can control any circuit-breaker located downstream,

even if it is not equipped with a measurement function. In installations that are already equipped with energy management

systems, the load limit can also be modified remotely.

SACE Emax 2 circuit-breakers are equipped with a new generation of protection trip units that are easy to programme and

read. The Ekip Touch trip units measure power and energy with precision and store the most recent alarms, events and

measurements in order to prevent faults to the installation or trip effectively when necessary. On request, the Network Analyzer

function is also available, which controls the quality of absorbed power in real time and with extreme precision.

In addition, the innovative Ekip Touch and Hi-Touch trip units in the G version include all the functions of generator protection

switchgear, offering a safe control solution that is ready to use. No external devices, wiring or inspections are required.
