This is a crucial safety switch that is compulsory in every photovoltaic power system, as stipulated by IEC 60364-7-712. The equivalent British standard, derived from BS7671 - Part 712.537.2.1.1, necessitates "the provision of means to isolate the PV converter from both the DC and AC sides for maintenance purposes."
The ONCCY DC Isolator is specifically engineered for disconnecting the DC side of solar inverters. In conjunction with other components, our switches ensure comprehensive protection against all forms of over-voltage and overloading. Enhanced with a unique arc extinguishing feature, we guarantee heightened safety, reliability, and extended service life.

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.
