Ltb 72.5-170d1 B | Manual
Provides a clear visual, mechanical indicator of whether the breaker is open or closed, as well as the spring state (charged/discharged).
If this is for a Siemens LTB 72.5kV breaker, the manual will cover SF6 gas handling, operating mechanism adjustments, and timing checks.
The product manual for the LTB 72.5-170D1/B generally includes the following sections: Product Description
: The uppermost chamber containing the fixed and moving primary paths, nominal current contacts, and the Auto-puffer™ piston assembly.
Preventive maintenance schedules (e.g., lubrication of the mechanism) and inspections of the SF6 gas quality. ltb 72.5-170d1 b manual
Always refer to the specific serial-number-linked manual provided by the manufacturer (e.g., Hitachi Energy/ABB) for the most accurate torque values and wiring diagrams.
Contains the motor, spring, tripping/closing coils, and terminal blocks. Density Monitor: Constantly monitors the SF6cap S cap F sub 6
Designed and tested in accordance with international standards like IEC .
Lubrication and mechanical checks of the operating mechanism (BLK 222), including springs and latch systems. Provides a clear visual, mechanical indicator of whether
Yes, the manual provides guidance on routine maintenance tasks that can be performed by the user. However, for complex repairs or maintenance, it's recommended to consult a professional.
The alphanumeric string LTB 72.5-170D1/B provides immediate information about the circuit breaker:
The first few pages of any manual are crucial for avoiding "out-of-box" failures.
The maintenance manual outlines specific care requirements to achieve a service life of over or 10,000 mechanical operations : LTB 72.5-170D1/B Circuit-Breaker Manual | PDF - Scribd Preventive maintenance schedules (e
Monitor the density gauge daily; SF6 leakage is toxic and harmful to the environment.
Never operate the breaker if gas pressure is below the minimum "blocking" level.
This specific model number does not return results for a major consumer brand (like Samsung, LG, or Lenovo). It strongly resembles the model format used by Leagoo or similar import smartphone manufacturers (often indicating a 6GB/128GB or similar spec configuration), or potentially a specific industrial component.
The unit is built to withstand extreme environmental conditions, from deserts to freezing climates, with a high degree of seismic resilience. Rated Voltage : 72.5 kV to 170 kV. Breaking Capacity : Up to 40 kA symmetrical short-circuit current. Continuous Current : Up to 3150 A.
