SIEMENS - SWITCH DISCONNECTORS
3KD Switch Disconnectors
3KD switch disconnectors
3KD switch disconnectors can be flexibly applied as main control, EMERGENCY-STOP, and maintenance switches. This is possible thanks to versatile connection options, operating mechanism designs, as well as an comprehensive range of accessories. The terminal covers ensure enhanced touch protection and prevent electric shock. Thanks to transparent covers, contact postions are clearly visible at all times. |
3LD Switch Disconnectors
3LD main control and EMERGENCY-STOP switching equipment
When power failures occur, our 3LD2 switch disconnectors safely disconnect and isolate electrical systems – and that applies to AC motors as well as air-conditioning systems and solar power installations. These switches have been proved in numerous applications, especially in the machine-building and conveyor system sectors and the chemical, food, and beverage industries. They’re certified as manually operated switch disconnectors in line with requirements specified by IEC 60947-3, DIN VDE 0660 Part 107, and EN 60947-3. According to DIN EN 60204-1, they can also be used as On/Off, EMERGENCY-STOP, and main control switches. Designs compliant with UL Standard 508 are available for international applications. In addition, variants certified to UL489 are available, which means that the switch can be used as the main switch for machines in the United States. |
3KF Switch Disconnectors with Fuse
3KF switch disconnectors with fuses
3KF switch disconnectors with fuses meet all the requirements for main control, EMERGENCY-STOP, and maintenance switches. They are designed to systematically prevent electrical accidents. For example, a suitable locking function during maintenance work prevents any unauthorized operation. These devices are simple to install, and additional functions can be easily retrofitted. Suitable LV HRC fuse links are available for up to 800 A. |
3NF Fuse Switch Disconnectors
3NP fuse switch disconnectors
The modular 3NP fuse switch disconnectors provide an extensive range of protection functions and convenient connection technology. The reach-around and touch protection, for example, prevents users from coming into contact with live parts when installing busbar systems, even when accessing unit rear-sides. The switches are available in five performance sizes up to 630 A and are very space-saving, thanks to their compact design. It’s easy to install these devices on mounting plates or rails or in busbar systems.
3KC Transfer Switch
3KC transfer switching equipment
3KC transfer switching equipment safely switch between two power sources and ensure continuous power supply if one power supply source fails. These devices can also switch between two loads and prevent operational failures. In addition to the automatic transfer switching equipment (3KC ATSE), a remote-controlled variant 3KC RTSE as well as a manually operated version 3KC MTSE are also available. The 3KC MTSE is suited for manual transfer switching operations up to 1,600 A between two grids or two electrical loads, and can be mechanically interlocked. Used in industrial and infrastructure applications, all of these transfer switching devices fulfill the requirements according to the IEC 60947-6-1 and IEC 60947-3 standards. |
Transfer switching equipment
A power failure can have serious consequences. The transfer switching equipment from Siemens enables safe switching between two power sources without interruption. The equipment consists of two switch disconnectors, ensures maximum protection with electrical and mechanical interlocks and meets the common IEC standards.
Indispensable for a continuous power supply
The 3KC transfer switching equipment ensures a continuous supply of power by switching between a main power source and an alternative power source. They can also be used for load transfer switching. The devices are characterized in particular by their simple installation and their safe, reliable operation.
With manually operated transfer switching equipment (MTSE), remotely operated transfer switching equipment (RTSE) and automatic transfer switching equipment (ATSE) versions in various sizes, the 3KC transfer switching equipment provides solutions for numerous switching tasks.

The 3KC ATC6300 and ATC 6500 transfer control devices
A power failure can have serious consequences
The 3KC ATC6300 and ATC 6500 transfer control devices enables safe and fault-free switching between two power sources. The 3KC is deployed above all where a mains failure can have critical consequences. In case of power supply faults, it switches from a main power supply to a standby power supply. In doing so, it safeguards an uninterruptible power supply.
