Functional Features: Drawout construction allows for safe removal for maintenance without de-energizing the entire lineup. Features LSIG (Long-time, Short-time, Instantaneous, Ground Fault) protection with zone-selective interlocking capability.

Application Scenarios: Main breakers in switchgear lineups for hospitals, data centers, and heavy industrial plants.

Structural Characteristics: Comprises a base (fixed part) and a truck (movable part). Includes primary and secondary disconnects, safety shutters, and mechanical interlocks.

Installation Requirements: Requires installation in a compatible GE switchgear frame. Proper alignment of the drawout rails is critical. Secondary control wiring must be connected to the test/connect block.

Precautions: Always use the racking lever to move the breaker between “Connected,” “Test,” and “Disconnected” positions. Ensure the breaker is fully locked into position before energizing.
