ZN85-40.5 three-phase indoor withdrawable vacuum circuit breaker
Three-phase indoor draw-out vacuum circuit breakers are specialized switching devices designed for indoor electrical distribution systems. These circuit breakers feature a draw-out design, allowing the breaker module to be easily inserted or withdrawn from the switchgear panel for maintenance or replacement purposes without de-energizing the entire system.
Utilizing vacuum interrupter technology, these circuit breakers offer good current interruption capabilities, effectively protecting the electrical system from overloads, short circuits, and other faults. Their modular and compact design makes them suitable for installation in substations, electrical rooms, and switchgear assemblies where space optimization is essential.
The draw-out feature enhances maintenance efficiency by reducing downtime and allowing for quick replacement or inspection of the circuit breaker module. With low maintenance requirements and a long operational lifespan, these vacuum circuit breakers provide high reliability and cost-effectiveness.
These circuit breakers can be integrated with advanced control and monitoring systems for remote operation, diagnostics, and condition monitoring, enhancing the automation and intelligence of the electrical distribution system.
