Components and solutions for photovoltaic systems - Weidmüller

Optimised efficiency
The optimised design of the junction box serves to
reduce the photovoltaic panels power loss and
thus improves the efficiency of the entire facility.
Robust, resistant connections
Panel connection
A new sealing and strain-relief system has significantly
increased the wire withdrawal forces in comparison with
the force needed for a conventional cable gland connection.
It is impossible to unintentionally loosen the connection
(automatic interlock).
Standard-compliant – TÜV and UL approvals
• Certified by TÜV Rheinland in accordance with
DIN V VDE 0126-5:2008.05 as well as the new
pr EN 50548
• UL approval in accordance with UL 1703
Optimised service
When servicing is required (for example, if a
cable has been bitten by a rodent), a new
connection can be made quickly, simply and
safely.
