These include twelve new models, six for the ISA range and six for the ISB range.

The ISB and ISA series of Cabur photovoltaic stringboxes have protections for the DC part of the plant.
These new models, compared to those already included in the catalog, are distinguished by the use of a DC automatic switch instead of the circuit breaker.

The ISA range photovoltaic stringboxes are supplied with a release coil for each switch to open the string circuit via an emergency button, as for the models with the circuit breaker.

The new products meet the increased power required by photovoltaic modules in use on the market, which increases the DC input current. They are suitable for panels with power ranging from 400 W to 700 W, with maximum input string current between 12 A and 16 A, depending on the photovoltaic stringboxes.

Cabur photovoltaic stringboxes are made in compliance with the EN IEC 61439-2 regulation and ready for installation, with significant savings in time and costs.
