As part of the trusted Siemens SENTRON 3LD2 Series, this switch disconnector is designed to meet the demanding requirements of industrial control panels, motor control centers, OEM machinery, power distribution systems, and automation installations. With its robust construction, door-coupling operation, and dependable switching capability, the 3LD2213-0TK51 delivers the safety and reliability expected from Siemens industrial products.
The Siemens 3LD2213-0TK51 is a 3-pole main switch disconnector rated at 32A, featuring an operating power rating of 11.5 kW at AC-23A, 400V. Designed for floor mounting with a door-coupling rotary operating mechanism, it allows safe switching operations from outside the control enclosure, helping improve operator safety and simplifying maintenance procedures.
One of the key advantages of the 3LD2213-0TK51 Switch Disconnector is its door-coupling rotary operating mechanism. This configuration allows users to operate the switch without opening the panel door, minimizing exposure to energized components and supporting safer working conditions. The black rotary handle provides smooth operation and clear visibility of switch positions, helping operators quickly identify whether the circuit is energized or isolated.
The Siemens SENTRON 3LD2 Series is widely recognized for its rugged construction and dependable performance. The 3LD2213-0TK51 is engineered for demanding industrial environments where reliable switching and safe isolation are essential. It is suitable for use as a:
Its versatility makes it a preferred choice for electrical contractors, panel builders, maintenance engineers, and industrial automation professionals.
Safety remains a major priority in industrial installations, and the 3LD2213-0TK51 is designed to support secure isolation procedures. The switch can be locked in the OFF position, making it suitable for lockout/tagout (LOTO) safety programs. This feature helps prevent accidental re-energization during maintenance activities and improves workplace safety compliance. Similar Siemens 3LD disconnectors support up to three padlocks for enhanced isolation security.
Another significant benefit of the Siemens 3LD2213-0TK51 is its IP65 front protection rating, providing strong resistance against dust ingress and water exposure. This makes the switch suitable for manufacturing plants, processing facilities, utility infrastructure, machinery installations, and other industrial environments where durability and environmental protection are critical.
The switch is designed with a rated insulation voltage of 690V AC and surge voltage resistance of 6kV, ensuring reliable operation in low-voltage power distribution and motor control systems. Its robust electrical characteristics support dependable switching performance while helping protect connected equipment.
The 3LD2213-0TK51 also delivers excellent mechanical durability. Siemens 3LD series switch disconnectors are designed for up to 100,000 mechanical operating cycles, helping reduce maintenance requirements and ensuring long service life in demanding industrial applications.
