The single-pole DC isolator switch is a crucial component widely used in various high-voltage DC disconnect applications, including inverters, subways, and high-speed rail systems. Designed to ensure the safety of equipment and personnel, this product can safely and effectively disconnect the inverter from the photovoltaic strings, ensuring the safe operation of the inverter.
In inverter applications, there are typically four DC switches, each controlling the DC terminal in its respective area. Manual operation allows the switch to be turned to the "OFF" position, disconnecting the DC input for convenient maintenance and inspection.
Beyond inverters, the single-pole DC isolator switch excels in high-voltage DC disconnect scenarios such as subways and high-speed rail systems. It supports multiple configurations, including 2P, 3P, 4P, 6P, 8P, 10P, and 2H/3H/4H, 4T/4B/4S, to meet diverse application needs.
Additionally, the product is UL certified, ensuring reliability and safety in various demanding environments.
