Siemens 3LD2213-0TK53 Three-Phase Disconnect Switch

Siemens 3LD2213-0TK53 is a 3‑pole SENTRON switch disconnector with emergency‑off function, designed to provide safe isolation in low‑voltage systems. This floor‑mounted unit uses a rotary operating mechanism and a red/yellow operator handle for clear visual indication of OFF, and is intended to install with a door coupling in panels or enclosures. It delivers a nominal current of 32 A (Iu) and, at 400 V AC with AC‑23 duty, handles about 11.5 kW of load, making it suitable for three‑phase isolation of equipment and machinery. The device is rated for insulation up to 690 V and offers a surge withstand of 6 kV, reinforcing its suitability for safety‑critical control circuits in industrial environments. As part of Siemens’ SENTRON 3LD family, it serves as a reliable disconnect switch with emergency switching capability, enabling safe maintenance and rapid isolation when required. The 3LD2213‑0TK53 configuration is designed for floor mounting with door coupling, ensuring secure integration into a cabinet or floor‑standing assembly and straightforward service access.
