GW1-12FR/630A-200A Outdoor Load High Voltage Isolator Switch

Engineered for stable medium-voltage performance in outdoor environments

The GW1-12FR Outdoor Load Isolator Switch is a medium-voltage isolator rated for 12kV and 630A/200A, purpose-built for overhead distribution lines in rural grids, substations, and renewable power installations. Designed for manual or motorized operation, this switch provides visible break isolation, robust arc-quenching capabilities, and safe load disconnection in all weather conditions.

✅ Key Features

Dual Current Ratings: Available in both 630A and 200A models to support various feeder or branch applications.
Visible Break Design: Ensures operational safety and fault detection through clear visual confirmation.
Arc-Suppressing Contacts: Equipped with arc horns and magnetic blowout features for secure disconnection under load.
Weatherproof Insulation: Insulating supports and porcelain or polymer bushings ensure durability under rain, frost, and dust.
Manual or Motorized Options: Can be fitted with a manual lever or motor actuator for remote SCADA system integration.
Fast Installation: Comes with a standardized mounting bracket for quick pole-mounting with minimal labor.
