Product Description

Solar DC Disconnect Switch

As of today, solar photovoltaic generates electricity in more than 100 countries and yet, despite constituting a tiny fraction of the 4800 GW total power-generating capacity from all sources, it is the fastest growing power- generation technology in the world.
Between 2004 and 2009, grid-connected photovoltaic capacity increased at an annual rate of 60%.

COET DC switch disconnectors for Photovoltaic applications are typically used in:

  • String boxes (1° level), for strings paralleling
  • Junction boxes, for string boxes paralleling
  • Inverter cubicles, for sectionalising

The line includes a range of compact size switch-disconnectors with very high DC performance: up to 1000Vdc from 20A to 800A.
Each model of the range has been fully type-tested at CESI laboratory according to EN60947-3 standards for categories DC21 and DC22.
Besides the line of switches for dc photovoltaic applications, COET is leader in Italy in manufacturing switches for ac voltage applications, in various switching categories.
