The Schelinger A02-G8-3P-B25 is a high-quality 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is specifically designed to detect and interrupt overcurrent conditions, effectively safeguarding wiring and connected equipment from the dangers of overloads and short circuits. With its reliable performance and standardized design, it serves as a critical component in modern electrical distribution boards.
Advantages
This miniature circuit breaker offers exceptional reliability and durability, ensuring long-term protection for your electrical infrastructure. Its B-type tripping characteristic makes it highly suitable for general applications where moderate inrush currents are expected. The 6kA breaking capacity provides a sufficient safety margin for standard domestic and light commercial installations, while the 3-pole configuration allows for the simultaneous disconnection of three phases, ensuring comprehensive safety during maintenance or fault conditions.
Suitable for
- Residential electrical distribution boards
- Commercial lighting and power circuits
- Protection of general-purpose electrical appliances
- Three-phase motor circuits with low inrush current
When it may not be suitable
This device is not intended for use in DC electrical systems, as it is specifically rated for AC operation. Furthermore, it may not be appropriate for circuits with high-starting-current equipment, such as large industrial motors or heavy-duty transformers, where a C or D-type tripping characteristic would be required to prevent nuisance tripping.
Key specifications
- Number of poles: 3
- Rated current: 25A
- Tripping characteristic: B
- Breaking capacity: 6kA
- Operating voltage 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 fastened to the terminals, maintaining the correct torque settings to prevent overheating. Once installed, the toggle switch can be used to manually energize or de-energize the circuit, and it will automatically trip to the off position in the event of an electrical fault.
What to consider before purchase
- Verify that the 25A current rating matches the load requirements of your circuit
- Ensure the B-type characteristic is appropriate for your specific connected devices
- Confirm that your distribution board has sufficient space for a 3-pole module
- Check that the 6kA breaking capacity meets the short-circuit current requirements of your installation site
Usage recommendations
Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a periodic test of the manual switching mechanism to ensure smooth operation. If the breaker trips frequently, investigate the circuit for potential overloads or faults before attempting to reset it.
