Product Description

The VB40.5-x/S90 is a high-performance circuit breaker integrated into the S90 series switchgear, designed for medium-voltage power distribution. It features one input and three configurable outputs, directly supporting up to four modular protection or metering units. Equipped with industrial-grade communication interfaces like Modbus RTU and IEC 61850, it operates within a voltage range of 24-48 V DC or 100-240 V AC and functions reliably across -25°C to +55°C. Ideal for utility grids, industrial plants, and renewable energy systems, the VB40.5 circuit breaker offers compact design, arc-resistant construction, and rapid fault interruption. Its integrated control panel includes a 4.3-inch LCD for real-time monitoring, while the S90 series switchgear architecture ensures seamless scalability. Drawbacks include higher installation complexity, offset by its 5000-cycle mechanical durability and 200 Ah backup battery for critical operations. Detection thresholds adapt dynamically for faults within 0.1-40.5 kV networks.
