If you are still stuck, consider contacting a specialized repair center for the LTB series. They often have internal documentation and can provide the specific parameter values or wiring pinouts over the phone.

The LTB 72.5-170D1 B manual is not merely a reference; it is a legally binding operational directive. It teaches that a circuit breaker is more than an electrical switch—it is a system of interlocks, gas density thresholds, and spring potential energy. Strict adherence to its torque values (e.g., 85 Nm for M12 terminal bolts) and its defined maintenance intervals guarantees 30+ years of service. Conversely, deviating from the "B" manual’s wiring diagrams (especially the anti-pumping circuit) will result in maloperations that can destabilize an entire transmission grid. For any substation engineer, this manual is the final authority on safety and reliability. ltb 72.5-170d1 b manual
