Featuring a 100A nominal current and 690V coil voltage, it is ideal for industrial control and safety applications. The unit comes with a distinctive red and yellow handle for high visibility. It operates at 50-60 Hz and offers a breaking capacity of 2000 A, ensuring reliable performance and protection in various electrical installations. ## Long description The Siemens 3LD2704-0TK53 is a professional-grade 3-pole load break switch engineered for reliable electrical circuit disconnection in industrial environments. This device serves as a main or emergency stop switch, providing a secure way to isolate power during maintenance or in critical safety situations. With a robust construction and a high-visibility red and yellow rotary actuator, it ensures that operators can quickly identify and access the control mechanism when needed. Advantages This load break switch offers exceptional durability and safety performance, meeting the rigorous demands of industrial electrical systems. Its design facilitates efficient power management with a nominal current of 100A and a power rating of 37kW at 400V. The inclusion of a clearly marked emergency stop handle enhances workplace safety by providing immediate visual indication of the switch status. Furthermore, the four-hole front mounting configuration allows for stable and secure installation on control panels or enclosures, ensuring long-term operational reliability. Suitable for Industrial machinery power disconnection Emergency stop applications in manufacturing plants Electrical distribution panels Maintenance isolation for heavy-duty equipment When it may not be suitable This device is not intended for use in environments exceeding its specified voltage or current ratings. It is also not suitable for applications requiring outdoor installation without an appropriate protective enclosure, as the standard mounting is designed for panel integration. Key specifications Number of poles: 3 Nominal current: 100A Operational voltage: 690V Power rating: 37kW at 400V Frequency: 50-60 Hz Mounting type: Front mounting, four-hole Actuator type: Rotary, red/yellow emergency stop Breaking capacity: 2000 A How to use The switch is designed for front panel mounting. Ensure the mounting surface is flat and capable of supporting the device weight. Secure the switch using the four-hole mounting pattern provided. Connect the electrical conductors to the terminals according to the wiring diagram, ensuring all connections are tightened to the specified torque. Once installed, the rotary handle can be turned to the '0' position to disconnect power or the '1' position to energize the circuit. What to consider before purchase Verify that the 100A current rating matches your circuit requirements. Ensure the panel space is sufficient for the four-hole mounting dimensions. Confirm that the red and yellow handle meets your facility's safety color-coding standards. Check that the operating environment is compatible with the switch's technical specifications. Usage recommendations Regularly inspect the switch for any signs of mechanical wear or loose connections. Ensure that the rotary actuator moves freely and that the emergency stop function is tested periodically to guarantee operational readiness. ## Specifications | Feature | Value | |---|---| | Nominal current output | 100 A | | AC input frequency | 50 - 60 | | Breaking capacity | 2000 A | | Number of modules | 1 | | Coil voltage | 690 V | | Coil voltage (min) | 400 V | | Coil voltage (max) | 6000 V | ### Weight & dimensions | Feature | Value | |---|---| | Weight | 0.497 kg | | Height | 107 mm | | Width | 90 mm | | Depth | 112.5 mm | ### Features | Feature | Value | |---|---| | Number of poles | 3P | ### Design | Feature | Value | |---|---| | Certification | CSA, UL, VDE, EAC, CE, LRS | | Product colour | Red, Yellow | ## FAQ ### How much does the Siemens 3LD2704-0TK53 3-Pole Load Break Switch 100A cost, and is it available for purchase?
