Note: Siemens documentation identifies 3LD2013-0TK51 as the SENTRON 3LD2, 3-pole main control/switch disconnector, not as the 1NO+1NC auxiliary switch itself. The standard 1NO + 1NC auxiliary switch associated with this device is 3LD9200-5C.
The Siemens 3LD2013-0TK51 is a SENTRON 3LD2 main control switch designed for manual switching and isolation in industrial electrical installations. It features a 3-pole configuration, 16 A uninterrupted current rating, black rotary operating mechanism and door-coupling arrangement with four-hole mounting. Siemens lists the device for main-switch, switch-disconnector, safety-switch and maintenance/repair-switch applications.
With its compact construction and robust industrial design, the 3LD2013-0TK51 can be used in machinery, electrical control panels, distribution equipment and industrial installations where reliable manual switching and isolation are required.
The Siemens 3LD2013-0TK51 can be used for:
The Siemens 3LD2013-0TK51 provides a practical solution for manually switching and isolating electrical equipment. Its rotary operating mechanism allows convenient operation, while the door-coupling arrangement makes it suitable for control-panel and enclosure applications.
The device is rated at 16 A and supports AC-23A operating applications, with Siemens documentation specifying up to 7.5 kW at 400 V depending on the applicable rating conditions.
For installations requiring auxiliary signalling, the compatible 3LD9200-5C auxiliary switch provides the 1NO + 1NC configuration referenced in Siemens product documentation.
Always verify the complete device configuration, electrical ratings, mounting requirements and applicable protection requirements before installation.
