## Summary description

The Etipo SSQ 440 is a 4-pole modular changeover switch designed for I-0-II switching between mains and generator power. Rated for 40A, this three-phase device is intended for DIN rail mounting in electrical distribution boards. It provides a reliable solution for manual power source selection, ensuring safe operation in residential and industrial electrical installations.

## Long description

The Etipo SSQ 440 is a high-quality 4-pole modular changeover switch engineered for seamless I-0-II switching between two power sources, such as the main electrical grid and a backup generator. Designed for three-phase systems, this device ensures reliable manual control over power distribution in both residential and industrial environments. Its compact modular design allows for efficient installation directly onto standard DIN rails within electrical distribution boards.
Advantages
This changeover switch offers a robust and dependable mechanism for manual power source selection, effectively preventing the simultaneous connection of two power supplies. Its modular construction facilitates easy integration into existing electrical panels, saving space and simplifying the wiring process. The device is built to handle significant electrical loads, providing a safe and durable solution for maintaining power continuity during grid outages.
Suitable for
Switching between mains power and backup generator supply
Residential electrical installations requiring emergency power backup
Industrial and commercial power distribution systems
Manual control of three-phase electrical circuits
When it may not be suitable
This device is not intended for automatic transfer switching; it requires manual operation to change the power source. It is also not suitable for applications exceeding its 40A current rating or for environments requiring specialized protection against extreme environmental conditions without a proper enclosure.
Key specifications
Number of poles: 4
Rated current: 40A
Switching positions: I-0-II
Mounting type: DIN rail
Phase compatibility: Three-phase
How to use
The switch should be installed by a qualified electrician within a suitable distribution board. Once mounted on the DIN rail, the input terminals are connected to the primary and secondary power sources, while the output terminals are connected to the load. The front-facing toggle allows the user to manually select between position I (mains), 0 (off), and II (generator), ensuring a clear physical break between sources.
What to consider before purchase
Verify that the 40A rating is sufficient for your total load requirements
Ensure the distribution board has enough space for a 4-pole modular device
Confirm that the installation environment meets the requirements for DIN rail equipment
Usage recommendations
Always ensure the switch is in the 0 (off) position before attempting to change power sources to prevent electrical arcing. Regular inspection of terminal connections is recommended to maintain optimal performance and safety.
