The fully enclosed, fully insulated, hermetically sealed distribution switchgear IE-RM6-24 with SF6 gas insulation is a modular metal-enclosed switchgear. This equipment can include modules such as a load switch, combined fuse unit, vacuum circuit breaker, and busbar input module. Using advanced technologies and materials, it offers excellent electrical and mechanical properties, is minimally affected by environmental and climatic conditions, has a compact size, is easy to install, convenient to operate, maintenance-free, and provides flexible configuration options.
With a clear and intuitive design, simple and direct operation, and high throughput, it is well-suited for various connection systems. All busbars of the IE-RM6-12/24 can be configured to support side wiring and side expansion, or top wiring and top expansion based on user requirements, maximizing flexibility to meet the needs of the power supply system.
