Description
SENTRON, ATE, transfer switching equipment 3KC, automatically, ATSE, 4- pole, Iu: 63 A, Ue AC: 415 V, Ie at AC-33 B at 415 V: 63 A, Ie at AC-23 A at 690 V: 63 A, screw and standard mounting rail on 35 mm, motorized operating mechanism, at the right end, long handle, box terminal 3KC transfer switching equipment up to 3200 A for permanent power supply. 3KC transfer switching equipment 3KC from SIEMENS stands for high performance, easy installation and reliable operation. In the portfolio, you will find manually operated MTSE, remotely operated RTSE and automatic ATSE transfer switching equipment in a variety of designs for a wide range of switching tasks. 3KC transfer switching equipment is used in power supply networks to transfer loads between a normal and an alternative source. Switching between two loads is also possible. 1. Short switching times for ASTE and RTSE (up to 160 A 180 ms). 2. Can be used flexibly thanks to a compact design and wide range of accessories. 3. Improved safety during maintenance works thanks to padlock locking. 4. Quick installation on the standard mounting rail with frame sizes up to 160 A. 5. Efficient engineering with extensive CAx data. 6. Simple documentation with the manual configurator. 7. Ideal for a continuous power supply (UPS) e.g. in computer rooms, production lines in continuous operation or large infrastructure such as airports (RTSE and ATSE variants).
