Siemens SION 3AE8 Product Features: Vacuum Interruption Technology: Employs a vacuum interrupter for current interruption, featuring stable arc-extinguishing performance, rapid dielectric recovery, and low contact wear. Reliable Short-Circuit Breaking Performance: Quickly interrupts short-circuit fault currents in medium-voltage systems, providing reliable protection for power distribution equipment and loads; specific breaking capacity depends on the 3AE8 model configuration. Long Mechanical Life: The operating mechanism is designed for long-term operation and repeated opening and closing, meeting the durability requirements of industrial and power distribution systems. Low Maintenance Design: The vacuum interrupter employs a sealed structure, eliminating the need for oil or gaseous arc-extinguishing media replenishment, reducing daily maintenance workload and lifecycle costs. Spring Energy Storage Operating Mechanism: Utilizes a mature energy storage operating mechanism, which can be configured with electric energy storage for rapid and stable opening and closing operations. Modular Structure: The circuit breaker body, operating mechanism, and secondary control accessories adopt a modular design concept, facilitating configuration, inspection, and maintenance. Fixed/Removable Installation Options: Installation methods can be tailored to the specific switchgear and project requirements, facilitating switchgear system integration. Comprehensive Auxiliary Accessories: Shunt trip units, closing coils, undervoltage trip units, auxiliary switches, anti-pumping devices, and phase-locking accessories can be configured according to specific models. Safety Interlocking Design: In removable switchgear, mechanical and electrical interlocks can be established with the chassis, grounding switch, and cabinet doors to enhance operational safety. Environmentally Friendly: Utilizing vacuum as the arc-extinguishing medium, it does not rely on SF₆ for arc extinguishing, reducing the environmental impact of the circuit breaker's arc-extinguishing system. High Operational Reliability: Suitable for medium-voltage power distribution systems requiring long-term continuous operation, meeting the needs of industrial, power, and infrastructure sectors. Wide Application Range: Can be used for the control and protection of feeders, transformers, motors, busbars, and industrial medium-voltage power distribution circuits. SION 3AE8 Key Selling Points: Vacuum arc extinguishing, high breaking performance, long mechanical life, low maintenance, spring energy storage mechanism, modular design, safety interlock, high reliability. Typical Applications: Suitable for medium-voltage switchgear, substations, industrial power distribution, power plants, mines, petrochemicals, infrastructure, transformer protection, and large motor control.
