When it may not be suitable
This circuit breaker is not intended for residential applications where a Type B tripping characteristic is typically required for standard lighting and socket circuits. It is also not suitable for direct current (DC) applications, as it is specifically designed for alternating current (AC) systems.
Key specifications
Number of poles: 3
Rated current: 20A
Tripping characteristic: Type C
Frequency: 50-60 Hz
Mounting type: Modular/DIN rail
How to use
The device should be installed by a qualified electrician into a compatible distribution board or consumer unit. It is designed to be mounted onto a standard DIN rail. Ensure that the supply voltage matches the specifications of the breaker before connection. Once mounted, the input and output cables should be securely terminated according to local electrical regulations to ensure proper contact and prevent overheating.
What to consider before purchase
Verify that the 20A rating is appropriate for your specific circuit load requirements.
Ensure the Type C characteristic matches the startup current of your connected devices.
Confirm that your distribution board has sufficient space for a 3-pole modular device.
Check that the installation environment meets the necessary safety standards for electrical equipment.
Usage recommendations
Always ensure the power supply is completely disconnected before attempting any installation or maintenance work on the circuit breaker. Regularly inspect the connections to ensure they remain tight and free from signs of thermal stress.
