SIPROTEC 7VU85

Why SIPROTEC 7VU85?

SIPROTEC 7VU85 is our compact, multifunction high speed busbar transfer (HSBT) device that rapidly transfers power for busbars with large inductive motors.

Power interruptions can cause motors to slow or stop, leading to productivity losses and safety risks. SIPROTEC 7VU85 continuously supervises power sources, automatically disconnecting faulty incomers and transferring the busbar load to an alternative source. Expect effective transfer to minimize production impact and prevent unplanned shutdowns.

The SIPROTEC 7VU85 accommodates the primary diagram of single busbar and sectionalized single busbar and double busbars with multiple incomers. The SIPROTEC 5 architecture offers full flexibility in hard and software for complex applications with up to 20 circuit breakers. Enjoy a safe, reliable power supply compliant with ANSI C50.41.

Key benefits

Keep operations running

Prevent significant economic losses and safety risks from power interruptions and maintain integrity during power source transitions.

Avoid unplanned shutdowns

Avoid expensive shutdowns in your industrial processes. Enable effective power transfers for reduced manufacturing and operational impact.

Maintain flexibility

Adapt the flexible SIPROTEC 5 architecture for a variety of industrial and power plant applications. Configure single, sectionalized or double busbars with multiple incomers, and apply predefined templates.

Featured capabilities

Ultra-fast switching times

Realize ultra-fast switching times up to 10ms with the improved 7VU85 algorithm. Achieve approximately 1ms closing times using high-speed binary output contacts for quick and efficient power supply transfers.

SIPROTEC 5 and DIGSI

Engineer complex applications with DIGSI, even for systems up to 20 circuit-breakers. SIPROTEC 5's flexible architecture provides protection and monitoring for diverse applications.
