SENTRON, 3KC transfer switch, manually operated, MTSE, size: 4, 3-pole, Iu: 500 A, Ue AC: 415 V, Ie at AC-33 B at 415V: 500 A, Ie at AC-23 A at 690V: 500 A, screw fastening, front drive, on the left end, without handle, busbar connection 3KC transfer switches up to 3200 A for permanent power supply. 3KC transfer switches from Siemens stand for high performance, easy installation and safe operation. 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 DIN 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). www.siemens.de/schaltgeraete. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe, efficient electrical infrastructure in buildings and industry.
