Renowned Manufacturer of Professional Solar DC Isolators
This essential safety switch is a vital component in every photovoltaic system, as mandated by IEC 60364-7-712. The British standard BS7671 - Part 712.537.2.1.1 also dictates that "To facilitate the maintenance of the PV converter, isolation means must be provided to disconnect the PV converter from both the DC side and the AC side."
Comprehensive Product Profile
The EDS6EL's screw fixing ensures uncompromised sealing performance; with multiple mechanical seals around the shaft, it guarantees a waterproof and moisture-proof design. Its stainless steel rotary screw remains rust-free and damp-resistant. Standard cable interfaces with seal rings, along with internal sealing in top and bottom covers secured by two screws, assure an IP66 protection degree.
Diverse Applications and Markets
This isolator switch plays a critical role in guaranteeing complete de-energization of electrical circuits for safe service or maintenance. The IP66 enclosures, among other options, are available to suit various inverter types. These switches are essential in electrical distribution systems, where the removal of power sources is necessary for equipment adjustments or repairs. Isolation switches are pivotal in substations to isolate apparatus like circuit breakers, transformers, and transmission lines for maintenance. These disconnectors focus on safety isolation rather than routine circuit control.
