Product Description

The VB 40.5-x-CSSM 19/S90 is a high-performance VB 40.5kV circuit breaker designed for medium-voltage power distribution systems. Integrated with the advanced VB CSSM vacuum breaker technology and the CSSM 19/S90 current sensor, it offers precise current detection up to 90kA, ensuring reliable fault protection. This device supports 3-phase inputs, 1 main output, and direct connections to monitoring modules via RS485 or IEC 61850 communication interfaces. Operating within 24-48VDC or 110-220VAC and a temperature range of -25°C to +60°C, it is ideal for substations, industrial plants, and renewable energy grids. Key advantages include compact design, low maintenance, and robust arc-quenching capability, while its higher initial cost may require budget considerations. The integrated CSSM 19/S90 sensor enables ±1% accuracy in current measurement across 10-4000A ranges.
