SGL DC 160A solar system Transfer Switch/electric manual changeover switch

Available from 160A-250A-630A(DC20) in 4P version, acting as a load break switches for DC current.

Especially indicated for installations for photovoltaic energy generators, which require a safe disconnection. Standard handle is supplied pad lockable in position “OFF” for maintenance. Bridging links available for series connections.

Also available under request.

Rated operational category

DC21/DC22 following IEC 60947-3

DC21: Resistive loads(moderate overloads included)

DC22:Resistive and reactive loads(inductive or capacitive)

Relevant characteristics for photovoltaic installations

Ui(V) rated insulation voltage (off load) I = 0A (equivalent to category of utilization DC20).

Uoc(V) Open circuit voltage of the photovoltaic system.

Uef(V) photovoltaic installation functioning voltage on load

Ief(A)Installation working current under load.

Icf(A) Short-circuit current of the photovoltaic installation.

In certain places of Pv Systems, reative component must be considered(cables, inverter, etc.).

The sizing of the switch must be done considering open circuit voltage as maximum operation voltage.

It necessary to comply with UI>Uoc. We recommend to set UI between 10 and 15% over Uoc. Ue≥Uef Ie≥Ief Ie≥Icf
