Siemens SIEM Mains Switch

The Siemens SIEM network switch, model 3KC3426-2AA22-0AA3, is a powerful and reliable relay switch designed for remote operation. With a rated current of 63 A and an input voltage of 415 V AC, this network switch is ideal for use in power supply networks. It enables load transfer between a normal and an alternative power source and can also be used for switching between two loads. The compact design and the option for mounting on a DIN rail make installation simple and efficient. The network switch is designed for continuous operation in critical applications such as data centers and large infrastructures where an uninterrupted power supply is required. Safety features, such as a padlock mechanism during maintenance, enhance operational safety and protect against unauthorized access. The 3KC network switch is therefore an excellent choice for demanding switching tasks.
