Expertly crafted for photovoltaic systems, this switch excels in providing reliable and efficient electrical isolation wherever it's critically needed.
Comprehensive Product Profile
The EDS6EL ensures exceptional sealing capabilities with its screw fixing system. Multiple mechanical seals guard the shaft, offering a waterproof and moisture-resistant architecture. Its stainless steel rotary screw resists rust and humidity. Standard cable interfaces with sealing rings, alongside top and bottom covers sealed with dual screws, guarantee an IP66 protection level.
This isolator switch is indispensable for achieving total de-energization of circuits, ensuring safe servicing or maintenance. The available IP66 enclosures, among other options, are compatible with various inverter models. Crucial for electrical distribution systems, these switches enable power disconnection for equipment servicing or adjustments. In substations, they isolate vital components like circuit breakers and transformers for maintenance, prioritizing safety isolation over routine control.
