Ensure the breaker frame and all relevant parts are securely grounded.

The problem: A slow SF6 leak at the bushing flange. The manual fix: Revision B introduced a new O-ring lubricant (Molykote 55). If you use generic grease, the seal will fail within a month. The manual specifies the exact lubricant and the tightening torque sequence (star pattern, 45 Nm).

The breaker consists of three separate poles, each equipped with its own interrupting chamber and mechanism connections. 3. Key Specifications (Based on Manual Data)
