Description

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.

Key Features:

  • Versatile Applications: Suitable for high-voltage DC disconnect applications in inverters, subways, and high-speed rail systems.
  • Multiple Configurations: Supports 2P, 3P, 4P, 6P, 8P, 10P, and 2H/3H/4H, 4T/4B/4S configurations.
  • Safety and Reliability: UL certified, ensuring high reliability and safety in various environments.
  • Manual Operation: Convenient manual operation design allows for quick disconnection of the DC input for maintenance and inspection.

Application Scenarios:

  1. Inverter Systems: Ensures safe operation and maintenance of inverters, preventing potential hazards.
  2. Subway and High-Speed Rail Systems: Provides reliable safety assurance in high-voltage DC disconnect scenarios.

With its high reliability, versatility, and safety design, the single-pole DC isolator switch is an ideal choice for high-voltage DC disconnect applications.
