In the portfolio you will find manually operated MTSE, remotely operated RTSE and automatic ATSE transfer switches in different designs for a wide range of switching tasks. 3KC transfer switches are used in energy supply networks to transfer loads between a normal and alternative source. Switching between two loads is also possible. 1. Short switching times for ATSE and RTSE (up to 160 A < 180 ms). 2. Flexible use thanks to compact design and extensive accessories. 3. Increased safety during maintenance work thanks to padlock lock. 4. Fast installation on the top hat rail for sizes up to 160 A. 5. Efficient engineering thanks to extensive CAx data. 6. Uncomplicated documentation with the manual configurator. 7. Ideal for continuous power supply (UPS), e.g. for computer rooms, production lines in continuous operation or large infrastructures such as airports (RTSE and ATSE variants).
