This is an essential safety switch and is mandated in each photovoltaic power system according to IEC 60364-7-712. The corresponding British requirement comes from BS7671 - Part 712.537.2.1.1, which states "To allow maintenance of the PV convertor, means of isolating the PV convertor from the DC side and the AC side must be provided".
Product Benefits
EDS1 series isolation switch is suitable for a power system with rated voltage DC 1200V or below and rated current 32A or below. The product can be used for infrequent switching-on and switching-off and can disconnect 1 - 2 MPPT lines at the same time. It is especially suitable for isolating lines in HVDC transmission and distribution systems, such as cutting off the high voltage DC current between solar panels and inverters
Advantages
Product Benefits
Isolator switch is used to ensure that an electrical circuit is completely de-energised for service or maintenance. IP66 enclosures and other options are available for your selection to meet a variety of inverters types. Such switches are often found in electrical distribution , where equipment must have its source of driving power removed for adjustment or repair. Isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers, transformers, and transmission lines, for maintenance. The disconnector is usually not intended for normal control of the circuit, but only for safety isolation.
