When it may not be suitable
This circuit breaker is not intended for high-inrush current applications, such as large motor starting or heavy industrial machinery, where a C or D curve characteristic would be required. Additionally, it is designed for single-phase systems and cannot be used for multi-phase circuit protection.
Key specifications
Rated current: 16A
Number of poles: 1
Breaking capacity: 6kA
Tripping characteristic: B
Design: Slim profile
How to use
The device is designed for standard DIN-rail mounting within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. The breaker is snapped onto the rail, and the supply and load wires are connected to the designated terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 16A rating matches the requirements of your specific circuit load.
Ensure the B-curve characteristic is appropriate for the connected equipment.
Check the available space in your distribution board to confirm compatibility with the slim design.
Confirm that the installation environment meets the technical requirements for this device.
Usage recommendations: Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to test the mechanical operation of the switch periodically to ensure it remains functional. Always ensure that the total load on the circuit does not exceed the 16A rating to prevent unnecessary tripping.
