## Long description

The Spamel ŁK40-3.8380OB3 is a high-performance 3-pole changeover switch engineered for reliable manual power management. Rated for 40A, this device facilitates seamless 1-0-2 switching operations, allowing users to safely toggle between two different power sources or circuit configurations. The switch is supplied in a durable protective enclosure, which provides essential insulation and physical protection against environmental factors, making it a dependable choice for demanding electrical installations.
Advantages
This changeover switch stands out due to its robust construction and high operational reliability in industrial environments. The integrated enclosure ensures that the internal components are shielded from dust and accidental contact, enhancing safety for the operator. Its 3-pole design allows for versatile application in three-phase systems, while the clear 1-0-2 switching logic prevents simultaneous connection of two power sources, effectively eliminating the risk of electrical feedback or short circuits during manual switching.
Suitable for
Industrial machinery power control
Switching between main power and backup generator supplies
Commercial electrical distribution panels
Manual control of three-phase motor circuits
When it may not be suitable
This device is not intended for applications requiring automatic transfer switching, as it is strictly a manual control unit. It is also not suitable for high-voltage environments exceeding its rated insulation parameters or for outdoor locations without additional weatherproofing protection.
Key specifications
Number of poles: 3
Rated current: 40A
Switching positions: 1-0-2
Mounting: Enclosed
Application: Manual circuit changeover
How to use
The switch is designed for manual operation via the front-mounted handle. To change the circuit state, rotate the handle to the desired position: 1 for the first source, 0 for the neutral/off position, and 2 for the second source. Ensure that the load is disconnected or minimized before switching to prevent arcing. Installation should be performed by a qualified electrician in accordance with local electrical codes, ensuring all cable connections are tightened to the specified torque.
What to consider before purchase
Verify that the 40A current rating is sufficient for your specific load requirements.
Ensure the 3-pole configuration matches your system's phase requirements.
Check the dimensions of the enclosure to ensure it fits your intended mounting space.
Confirm that the manual 1-0-2 operation meets your operational needs for power source selection.
Usage recommendations
Always ensure the switch is in the 0 (off) position before performing any maintenance on the connected circuits. Regularly inspect the enclosure for signs of physical damage or loose wiring to maintain optimal safety standards.
