Properties and Uses of the Product
This load break switch is designed for reliable operation in various distribution system applications, ensuring minimal energy losses and often exceeding standard efficiency ratings.
Key Features
- Vacuum Interrupters: The core technology involves vacuum interrupters that extinguish arcs without the need for oil or gas, which are common in traditional circuit breakers.
- Insulation Medium: The switch part uses VI (vacuum) for insulation, while the conduction part is insulated with Epoxy.
- Operation Mechanism: Features a magnetic actuator for precise and reliable switching operations.
- Control Circuit: Operates with AC230V or DC24V power.
