Suitable for
Residential electrical distribution boards
Commercial building power management systems
Industrial control panels and machinery circuits
Safe isolation of lighting and heating loads
When it may not be suitable
This device is not intended for use as a circuit breaker, as it does not provide overcurrent or short-circuit protection. It should not be installed in applications where automatic protection against electrical faults is required without being paired with appropriate fuses or miniature circuit breakers.
Key specifications
Rated operational current: 40A
Number of poles: 4
Mounting type: DIN rail
Operational voltage: Suitable for standard low-voltage distribution systems
Device type: Modular switch-disconnector
How to use
The device is designed for mounting on a standard 35mm DIN rail within an electrical enclosure. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Once mounted, connect the incoming power supply to the top terminals and the outgoing load to the bottom terminals, ensuring all connections are tightened to the specified torque. The toggle switch on the front panel allows for manual operation to connect or disconnect the power supply to the downstream circuit.
What to consider before purchase
Verify that the 40A current rating is sufficient for your specific load requirements.
Ensure the 4-pole configuration matches your electrical system architecture.
Confirm that the enclosure has sufficient space on the DIN rail for the modular width.
Check that the device is compatible with the intended voltage levels of your installation.
Usage recommendations
Always ensure the device is operated within its rated parameters to maintain safety and longevity. Regular inspection of the terminal connections is recommended to ensure they remain secure and free from oxidation over time.
