INOSYS LBS : The perfect combination of proven switch technology with remote tripping function

Socomec manufactures a unique and innovative solution for the protection of electrical facilities and offers a full range of load break switches with disconnection (for AC and DC current).

Whilst retaining the essential features that contributed to the success and reputation of the SIRCO range, the INOSYS LBS load break switches today offer users a real technological leap forward.
By integrating a tripping function that allows remote emergency switching, we offers a major advance to users of load break switches.

  • Why choose a load break switch designed for photovoltaic applications?

    • Safe operations

      To ensure electrical separation during maintenance operations, or for emergency breaking to prevent a risk of fire or electrical shock, it is essential that dedicated photovoltaic switches are used.
      These devices must be installed at each functional level of the installation based on its architecture.
      In order to disconnect a direct current photovoltaic string, generator or UpS, only SIRCO PV or SIRCO MC PV devices can:
      • Isolate the associated high DC voltages ,
      • guarantee safe on-load disconnection several thousand times across the full range of DC currents linked to daily fluctuations in sunlight, up to 1500 VDC.

    • Devices designed for extreme conditions

      SIRCOs have been designed for industrial use. They are extremely robust, with casings made from glass fibre-reinforced thermoset materials, bringing numerous benefits:
      • Stable temperatures, unlike some thermoplastics,
      • Excellent resistance to high temperatures,
      • good electrical characteristics: Arc and insulation resistance,
      • good mechanical characteristics: Dimensional stability and rigidity over time.
      These benefits are particularly important in photovoltaic installations, where the temperature may be below 0°C or above 50°C.

    • Back-to-back design, an innovative solution

      The SOCOMEC range of photovoltaic load break switches enables simultaneous on-load disconnection of two circuits using a single handle.
      Advantages
      • Space saving: The overall width is the same as that of 3 or 4 pole devices. This enables significant savings, as compared to the use of two separate devices.
      • Simple connection and integration.
      • Increasing the voltage: Connecting the two devices in series allows on-load disconnection of voltages above 1000 VDC.
      • Doubling the rating: by connecting the two devices in parallel.                                                                                                                                                                                                      

    • What are the standards that apply to photovoltaic installations?

      For installations

      Photovoltaic installations are governed by international standards such as IEC and UL. These standards provide the guidelines for commissioning a photovoltaic installation.
      • IEC 60364-7-712: Electrical installations of buildings
      — Requirements for special installations or locations — Solar photovoltaic (PV) power supply systems.
      • IEC 62548: Installation and safety requirements for photovoltaic (PV) generators.

       

      For breaking devices
      To date there is no specific IEC logo_156_01.png  logo_157_01.png
      standard.
      Manufacturers must therefore refer to standard
      IEC 60947-3. In the USA, the reference standard is UL98B. This standard, which is more stringent than IEC 60947-3, requires strict testing, in particular concerning temperatures and resistance to
      electrical arcing.
      SIRCO PVs have been developed in compliance with both IEC 60947-3 and UL98B.
       

       

    • PV Arc-Fault & String Monitoring System

      Defective PV modules and components – as well as faulty cables or connectors – can lead to potentially dangerous arc-faults. Undetected, an arc-fault could result in an electrical fire, causing damage to the PV installation and surrounding property.
      RESYS AFD - Arc Fault Detection & String Monitoring system - is a compact solution for integration within a PV combiner box, designed to detect and interrupt an electrical arc before it results in a potential fire. It also monitors the PV energy production at string level to reduce energy losses and guarantee the return on investment of the PV plant.

       

      INOSYS LBS combined with RESYS AFD provide a fully tested and certified Arc Fault Detection and Interruption system, together with string monitoring and rapid shutdown function.
