DC isolator switch is designed for DC power distribution systems where safe and visible isolation is required. It is suitable for DC operating voltages commonly used in photovoltaic and energy storage systems, such as DC 250V, 500V, 750V, and up to 1000V, depending on the model configuration.The switch supports a wide range of rated currents, typically from 16A to 160A or higher, allowing flexible selection for different DC circuit capacities. It is available in multiple pole configurations, such as 2P, 3P, and 4P, ensuring complete isolation of conductors in various DC system designs.The DC isolator switch adopts a manual operating mechanism, usually a rotary handle, with clear I / O (ON / OFF) position indication. It is intended for isolation purposes only and does not provide overload or short-circuit protection. Therefore, it is normally used together with DC circuit breakers or DC fuses to form a complete protection and isolation solution.With a robust enclosure and stable mechanical performance, the switch is suitable for installation in distribution boxes, control panels, and outdoor enclosures. Depending on the application, products may offer different protection levels (such as IP20 to IP65), making them suitable for both indoor and outdoor DC installations. The DC isolator switch is widely applied in photovoltaic arrays, battery systems, and industrial DC power networks where safe circuit isolation is required.
