Intelligent Fault Detection & Isolation: The integrated "viewdog" function can automatically detect and isolate single-phase ground faults and phase-to-phase short-circuit faults within a user's branch line, preventing localized faults from causing outages on the entire main distribution line.
Robust Sealed Structure: The breaker's internal components are sealed, which helps improve moisture and condensation resistance, making it suitable for harsh environments. Some models use SF6 gas for insulation.
Flexible Operation and Control: It supports electric energy storage and electric opening/closing, and can also be operated manually. When paired with a controller, it enables remote control, measurement, signaling, and regulation for distribution automation.
High Reliability Mechanism: The spring operating mechanism has been miniaturized and optimized, significantly improving its reliability compared to traditional designs.
Typical Applications: It is widely used for protection and control in power distribution networks, industrial plants, and mining facilities, especially in locations that require frequent switching operations.
