Woehner USA says it is now offering Telergon's S5000 DC load break switches, which are ETL-recognized to the UL 98B standard at 1,000 VDC. The company is the official distributor for the complete range of Telergon photovoltaic switches in North America.
Telergon's S5000 DC load break switches are aimed at North American photovoltaic installations that require NRTL (Nationally Recognized Test Laboratory) certification. They are typically used in string combiner boxes, re-combiner boxes and inverters that are constructed to the UL 1741 standard and can be used to safely disconnect live direct current at up to 1,000 VDC.
The switches are currently available in four models: Size 1 (250 A), Size 2 (400 A), Size 3 (700 A) and Size 4 (1,250 A).
