When it may not be suitable

This device is not intended for use in DC electrical systems, as it is specifically rated for AC applications. Furthermore, it may not be appropriate for circuits with high inrush currents that require a D-type tripping characteristic, such as large motors or transformers.

Key specifications

• Number of poles: 3
• Rated current: 20A
• Tripping characteristic: C
• Breaking capacity: 6kA
• System type: AC

How to use

The circuit breaker should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a distribution enclosure. Ensure that the supply cables are securely connected to the input terminals and that the load circuits are connected to the output terminals, maintaining proper torque settings to prevent loose connections.

What to consider before purchase

• Verify that the 20A rated current matches the requirements of your specific circuit load.
• Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that the 3-pole configuration is compatible with your three-phase electrical system.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform a functional test of the tripping mechanism periodically to ensure continued operational safety.
