The Siemens 3LD2222-0TK13 Emergency Stop Switch is a high-performance switch disconnector engineered to provide safe electrical isolation, emergency shutdown capability, and reliable switching performance in industrial environments. As part of the trusted Siemens SENTRON 3LD Series, this emergency switching-off switch is designed to protect personnel, machinery, and electrical systems by enabling rapid disconnection of power during maintenance, servicing, or emergency situations. With its rugged construction, IP65 protection rating, and proven Siemens reliability, the 3LD2222-0TK13 is an ideal solution for industrial control panels, power distribution systems, OEM machinery, and automation applications.
The Siemens 3LD2222-0TK13 is a 3-pole emergency switching-off switch with a rated operational current of 32A and an operational power rating of 11.5 kW at AC-23A, 400V. It features a front-mounted design with a highly visible red and yellow rotary operating handle, ensuring quick identification and operation during emergency conditions. Siemens specifically classifies this model as an EMERGENCY-OFF switch, making it suitable for safety-critical industrial installations.
One of the key advantages of the 3LD2222-0TK13 Emergency Stop Switch is its versatility. Siemens confirms that this switch is suitable for use as:
This multi-functional capability allows system designers and panel builders to use a single device across a wide range of industrial safety and isolation applications.
The switch incorporates a knob-operated rotary mechanism with clearly marked 1 (ON) and 0 (OFF) positions. The red/yellow handle design follows internationally recognized safety conventions, enabling operators to quickly identify emergency isolation devices and react promptly during critical situations. The front-mounted 4-hole fixing arrangement also ensures secure installation and long-term mechanical stability.
A major benefit of the Siemens 3LD2222-0TK13 is its outstanding environmental protection. The switch offers IP65 protection on the front, providing excellent resistance against dust ingress and water exposure. Siemens also specifies NEMA 1, 3R, 4X, and 12 protection ratings, making the switch suitable for harsh industrial environments, manufacturing facilities, processing plants, and infrastructure projects.
The 3LD2222-0TK13 is built for durability and long service life. Siemens specifies a typical mechanical life of 100,000 operating cycles and electrical endurance of up to 6,000 operating cycles at AC-23A, 690V, ensuring dependable performance even in demanding switching applications. This robust construction helps reduce maintenance costs and supports long-term operational reliability.
Safety is further enhanced through the switch's ability to be locked in the OFF position, supporting lockout/tagout (LOTO) procedures. This feature helps maintenance personnel safely isolate equipment before servicing and contributes to compliance with workplace safety standards.
The switch is designed with a rated insulation voltage of 690V and surge voltage resistance of 6kV, enabling reliable operation in industrial power systems. Additionally, it offers a conditional short-circuit withstand capability of 50kA when protected by an appropriate gG fuse, enhancing overall system protection and reliability.
