VOOB8-B
Key Features and Advantages
The VOOB8-B 12004-106-04 features arc-quenching technology achieving 3ms fault clearance in metro traction systems. Dual redundant control coils ensure fail-safe operation under vibration (EN 61373 certified). Integrated temperature sensors enable predictive maintenance via real-time contact wear analysis. The vacuum interrupter design eliminates SF6 gas dependency, complying with EU F-Gas regulations. SIL 4-certified logic ensures railway safety integrity level requirements.
Application Areas
Critical for high-speed rail traction power systems, the VOOB8-B 12004-106-04 protects 25kV AC catenary networks during short circuits. Metro operators utilize its EN 50155 compliance for underground rolling stock protection. Renewable energy plants integrate the breaker for DC busbar protection in solar farms. The -40°C operational rating ensures reliability in arctic rail corridors.
