Circuit Breaker Type A Brennenstuhl 1290660

The Circuit Breaker Type A Brennenstuhl 1290660 is a residual-current device designed to enhance electrical safety in installations that require Type A protection. It accepts a 16 A input current and operates at a nominal 230 V input voltage. Classified as Type D for specific tripping characteristics and carrying an IP54 ingress protection rating, this device provides protection against contact with limited dust ingress and water splashes. The unit is finished in yellow, allowing for clear visual identification in electrical panels or distribution points.

Advantages

This circuit breaker provides selective residual-current detection for both AC and pulsating DC fault currents, consistent with Type A functionality. The 16 A rating and 230 V nominal voltage make it compatible with standard single-phase circuits. The Type D classification describes its tripping characteristic which can be relevant in installations with certain types of loads. The IP54 rating ensures a basic level of protection against dust and splash water, extending suitability to indoor utility areas and semi-protected outdoor locations. The yellow housing improves visibility for maintenance and identification purposes.

Suitable for

• Protection of single-phase circuits with 230 V supply and up to 16 A load
• Electrical installations requiring Type A residual-current detection
• Utility rooms, workshops, garages, and semi-protected outdoor distribution points
• Installations where visible device identification is desired

Key specifications

• Residual-current type: Type A
• Tripping characteristic: Type D classification
• Rated current: 16 A
• Rated voltage: 230 V (nominal)
• Ingress protection: IP54 (protection against limited dust ingress and water splashes)

How to use

Install the Circuit Breaker Type A Brennenstuhl 1290660 in accordance with local electrical codes and the wiring diagram of the installation. Ensure power is disconnected before mounting. Connect the incoming phase and neutral conductors to the designated terminals and secure all connections to the torque values recommended for the installation. After installation, restore power and test the device using a suitable RCD tester or by following the standard test procedure to confirm correct operation.

Recommendations

Use this device as part of a complete protective scheme: pair it with appropriately rated overcurrent protection and ensure periodic testing and inspection. Avoid installation in locations subject to heavy water jets or full immersion despite the IP54 rating. For environments with higher ingress or special load characteristics, consult a qualified electrician to confirm suitability.
