The Siemens 3LD2064-0TB53 Emergency Stop Switch is a reliable and compact switch disconnector designed to provide safe electrical isolation, emergency shutdown capability, and dependable switching performance for industrial applications. As part of the renowned Siemens SENTRON 3LD2 Series, this emergency switching-off switch is engineered to protect personnel, equipment, and electrical systems by ensuring rapid disconnection of power whenever emergency conditions, maintenance activities, or servicing operations require complete circuit isolation. The rugged enclosed design and industrial-grade construction make it an ideal solution for machinery, automation systems, electrical panels, and power distribution installations.
The Siemens 3LD2064-0TB53 is a 3-pole emergency switching-off switch with a rated operational current of 16A and an operating power rating of 7.5 kW at AC-23A, 400V. It is supplied in a durable molded-plastic enclosure and features a highly visible red/yellow rotary operating handle, enabling quick identification and operation during emergency situations. Siemens specifically classifies this model as an emergency switching-off switch within the SENTRON switch disconnector portfolio.
One of the key benefits of the 3LD2064-0TB53 Emergency Stop Switch is its ability to serve multiple industrial functions. The switch is suitable for use as:
This versatility allows panel builders, system integrators, and maintenance professionals to standardize isolation and safety solutions throughout industrial facilities.
The switch incorporates a rotary operating mechanism with a short rotary knob and a clearly visible red/yellow handle. The internationally recognized emergency-stop color scheme helps operators quickly identify the switch during critical situations, improving response times and enhancing workplace safety. Clear ON/OFF position indication further supports safe operation and system control.
A major advantage of the Siemens 3LD2064-0TB53 is its enclosed construction. The molded-plastic enclosure provides additional protection for internal switching components while helping prevent accidental contact with energized parts. The enclosure is designed for metric cable gland entry and supports reliable operation in demanding industrial environments.
The switch offers an IP65 protection rating, providing excellent resistance against dust ingress and water exposure. This high level of environmental protection makes the device suitable for manufacturing plants, processing facilities, OEM machinery, utility infrastructure projects, and outdoor industrial applications where reliability is essential.
The 3LD2064-0TB53 is designed for long-term durability and dependable operation. Siemens engineers the SENTRON 3LD2 Series to withstand demanding industrial conditions while maintaining reliable switching performance throughout its service life. The switch supports operation in temperatures ranging from -25°C to +55°C, making it suitable for a wide range of industrial environments.
Safety is further enhanced through support for lockout/tagout (LOTO) procedures. The switch can be secured in the OFF position, helping maintenance personnel safely isolate equipment before servicing. This feature reduces the risk of accidental energization and supports compliance with industrial safety requirements.
With a rated operational voltage of 690V AC, rated current of 16A, and operating power of 7.5 kW, the Siemens 3LD2064-0TB53 Emergency Stop Switch delivers dependable performance for motor isolation, machinery shutdown, and power distribution applications. Its compact footprint, enclosed design, and robust construction make it a preferred choice for industrial control and safety installations.
