Product introduction
The AIERWAY QH-24JYT-A1 is a high-performance, indoor-mounted medium-voltage vacuum circuit breaker (VCB) switchgear designed for 24kV power distribution systems. As part of the JYT series, it incorporates advanced vacuum interruption technology within a metal-enclosed, compartmentalized structure, providing reliable protection, control, and isolation for transformers, feeders, motors, and capacitor banks in industrial, commercial, and utility applications.
Key Features & Advantages
– High Breaking Capacity: Suitable for networks with high fault levels (up to 40kA).
– Safety & Reliability: Compartmentalization, interlocks, and visible isolation ensure operator safety and system integrity.
– Flexible Configuration: Can be supplied as individual breaker panels or assembled into multi-panel switchgear lineups.
– International Compatibility: Designed for 24kV systems common in global markets (Europe, Asia, Middle East, etc.).
– Eco-Friendly: No SF₆ gas or oil; vacuum interruption is clean and maintenance-free.
