## Long description

The Hager SFT140 is a professional-grade modular changeover switch designed for precise electrical circuit management. Engineered for reliability, this 1-pole device operates at 230V and is rated for a 40A current, making it an essential component for manual power source selection or circuit isolation within electrical distribution boards. Its compact modular design ensures seamless integration into standard DIN-rail systems, providing a robust solution for both residential and commercial electrical infrastructure.
Advantages
This changeover switch offers exceptional durability and operational safety, meeting rigorous industry standards for electrical components. The manual switching mechanism provides clear and tactile feedback, ensuring that users can reliably toggle between two power sources or circuits without risk of overlap. Its modular construction simplifies installation and maintenance, while the high-quality materials used in its manufacturing guarantee long-term performance and resistance to electrical wear in demanding environments.
Suitable for
Manual switching between main power and backup generator sources
Isolating specific electrical circuits for maintenance or safety purposes
Managing power distribution in residential consumer units
Controlling circuit inputs in commercial electrical panels
When it may not be suitable
This device is not intended for automatic switching applications or remote control operations, as it requires manual intervention to change positions. It is also not suitable for high-voltage industrial applications exceeding its 230V rating or for circuits requiring more than one pole of disconnection.
Key specifications
Rated current: 40A
Voltage: 230V
Number of poles: 1
Mounting type: DIN-rail
Switching positions: I-0-II
How to use
The Hager SFT140 should be installed by a qualified electrician into a standard electrical distribution board on a DIN-rail. Once installed, the switch is operated manually via the front-facing toggle. The three-position mechanism allows the user to select between circuit one, the off position, or circuit two. Ensure that the load is disconnected or minimized before switching to prevent electrical arcing.
What to consider before purchase
Verify that the 40A current rating is sufficient for your specific circuit load
Ensure the 1-pole configuration meets your electrical system requirements
Confirm that there is adequate space on your DIN-rail for a modular device
Check that the operating voltage of 230V matches your local power supply
Usage recommendations
Always ensure the switch is fully seated in the desired position to maintain a stable electrical connection. Periodically inspect the terminals for tightness to prevent overheating and ensure the device remains free of dust and debris.
