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:
EDS6EL Screw fixing doesn't interfere with the sealing performance; Multiple mechanical seals around the shaft guarantee the reliability of a waterproof and moisture-proof design; Stainless steel rotary screw does not rust nor damp; Standard cable interface available with seal rings; Internal sealing in top and bottom covers, combined with 2 screws, guarantee an IP66 protection degree.
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.
