Part Number: 158574
CiPlug2-51-1
  • Generator junction box for 2 MPP tracker / 4 strings
  • Integrated surge protection device
  • Protection class IP65
  • Connection via MC4-connectors

With the new CiPlug string box, CITEL is providing a solution to protect the DC side of small and medium-sized Photovoltaic (PV) systems against the effects of surges and overvoltages. With its small dimensions, the CiPlug is ideal for rooftop installations in the residential building sector. The CiPlug includes pre-assembled pv-cables equipped with MC4 plugs, which enables a very fast and easy installation. With its maximum system voltage (Ucpv) of 1200 Vdc, it is applicable for any common configuration and reliably protects the MPP tracker of the inverter. Depending on the configuration, the CiPlug meets the normative requirements for all types of buildings with or without external lightning protection system up to lightning protection class I (Iimp = 12.5 kA / pole (10/350)).
