Emax 2 integrates both standard and advanced microgrid functionalities to meet a broad range of on/off grid requirements, improving flexibility and saving costs.
Emax 2 reduces switchboard footprint thanks to material and space saving up to 30%.Package selling model guarantees modularity and flexibility in each project.
Emax 2 protects 100% loads and generators in on/off grid conditions thanks to its built-in complete set protections.One single product ensures access to energy monitoring and advanced functionalities.
Emax 2 optimizes conventional and renewable power sources with energy storage systems ensuring reduction of CO 2 emissions.Power management reduces electricity peak and cost up to 20%.
The connection of a generator to a low voltage microgrid or to a medium voltage network through a transformer adds specific protection requirements.
Examples are machine's protections and synchronism between generators and grid. Typical uses are marine and distribution applications.
Emax 2 Generator protection trip units offer a wide set of new protections and parallel check.

Vessel is a microgrid application in island mode where reliability and service continuity are key elements.
Zone selectivity is the most advanced methods for making fast coordination.It is based on a network where all devices can send and receive signal each other. The breaker closest to the fault takes action and informs others to continue working.
Emax 2 guarantees the highest level of reliability thanks to Redundant Zone Selectivity based on two coordination network: electrical and digital (Ethernet).
The transition from ON grid to OFF grid modifies the network configuration and short circuit requirement.
The most representative application is a microgrid with utility supply (ON grid) and generator emergency supply (OFF grid).
Emax 2 adapts protections settings for each scenario, guaranteeing coordination in any condition.
Interface protection based on voltage and frequency are required to disconnect the microgrid from the main grid.
Automatic re-closure reconnect the microgrid to the main grid according to synchrocheck conditions and switching logics.
Emax 2 is the breaker at the microrgid point of common coupling which includes these functions in compliance with international standards.
Service continuity in microgrid is essential.
The automatic transfer switch logic manages the supply from the main line to a local generator line in case of faulty conditions in the utility network.
Emax 2 is the first circuit breaker with embedded programmable logic able to manage automatic transfer switch function.
Emax 2 new functions maximize service continuity and enable to reduce by up to 30% the switchgear.
Interlock functions increase electrical system reliability and people safety in LV microgrid connected to MV grid.
Case 1: Emax 2 distinguishes the earth fault type (Restricted and Unrestricted) and with programmable contacts can command the MV opening, without additional external relays.
Case 2: when the MV breaker trips, the LV breaker is required to open avoiding reverse fault power supply. Using Emax 2 communication protocols or programmable contacts is possible to interlock MV and LV sides.

The embedded algorithm in Emax 2 manages active and reactive power using feedback from microgrid generation and storage resources.
ON grid, power absorption is controlled at microgrid point of common coupling for daily power profile consumption definition, busbar voltage support and power microgrid factor definition.
OFF grid, microgrid power is balanced between load and generation to save fuel and reduce CO2 emissions.
Peak Shaving and Load Shifting solution to control microgrid power flow, reduce maximum demand charges and optimize the plant absorption.
Ready for virtual power plant (aggregation of clients and loads) and demand response programs thanks to communication protocols.
Load management patented algorithm is embedded in Emax 2. Discover more >
Load shedding can support the islanding microgrid during the transition from ON grid to OFF grid or the steady state.
Emax 2 using rate of change of frequency function -ROCOF- disconnects loads only in case of emergency unbalance condition.
Emax 2 realizes the load shedding logics thanks to digital contacts embedded in the breaker or externally installed in Din Rail modules.
