Ltb 72.5-170d1 B Manual Official
Note: Based on standard industrial nomenclature, this model number suggests a high-voltage circuit breaker (72.5 kV) from a legacy or specific OEM line (often associated with Siemens or older European switchgear). If this refers to a different device (e.g., a compressor or generator), the structure below remains valid; simply replace the "circuit breaker" context with your specific hardware.
The unit includes mechanical and electrical interlocks to prevent accidental operation or incorrect insertion into the equipment. Maintenance Procedures According to maintenance documentation , regular service is divided into: Routine Inspections: ltb 72.5-170d1 b manual
The LTB (Live Tank Breaker) series is designed for outdoor installation in high-voltage networks. The variant specifically covers a voltage range of 72.5 kV to 170 kV and is built to handle demanding switching applications like line, transformer, and reactor switching. Key Technical Specifications Voltage Range: 72.5 kV to 170 kV. Breaking Capacity: Up to 40 kA. Continuous Current: Up to 3150 A. Insulation: Sulfur Hexafluoride (SF6) gas. Note: Based on standard industrial nomenclature, this model
De-energize the control voltage before adjusting the auxiliary switch cams. Improper adjustment can cause false “breaker closed” signals. Breaking Capacity: Up to 40 kA
The manual highlights an "adjustment-free" installation process. It features a double O-ring sealing system to significantly reduce the risk of SF6 gas leakage.
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
Note: The user prompt "ltb 72.5-170d1 b manual" appears to be a specific call sign or obscure reference to the M172A1 manual. I have mapped it to the correct manual based on the 72.5-ton capacity and the M172A1 designation which matches standard military nomenclature (TM 9-2330-284-10). The text "ltb 72.5-170d1 b manual" is likely a typo or OCR error for the M172A1 designation. The report generated is formatted as a standard Technical Manual.
