Miniature circuit breaker Brennenstuhl 1290670

Miniature circuit breaker Brennenstuhl 1290670 is a Type A residual-current device designed for outdoor use with an IP55 rating. It provides immediate disconnection of the live conductor when residual current is detected and is supplied in blister packaging. The device has a nominal voltage of 230 V and a nominal current of 16 A; it is a 2-pole cut-out suitable for connection to small flexible cables and uses the DE plug-in system. The product colour is yellow.

Advantages

This Brennenstuhl miniature circuit breaker offers residual-current protection (30 mA) to reduce the risk of electric shock. Its IP55 enclosure permits installation in outdoor environments where protection against dust and water jets is required. The 2-pole design ensures both live and neutral are disconnected, and the compact plug-in system simplifies replacement and installation.

Suitable for

• Outdoor power outlets and temporary outdoor equipment
• Frequently used electrical appliances and hand tools
• Small flex cable connections (3G0.75 mm² to 3G1.5 mm²)
• Residential and light-commercial electrical circuits requiring Type A RCD protection

How to use

Install the miniature circuit breaker according to local electrical regulations and manufacturer instructions. Connect the live and neutral conductors to the two poles, ensuring cable sizes are within the specified range (3G0.75 mm² to 3G1.5 mm²). Ensure the device is mounted and sealed appropriately for outdoor conditions to maintain the IP55 rating. Test the device after installation by using its test function or following standard commissioning procedures.

Recommendations

Periodically test the residual-current function (typically every three months) and inspect the enclosure for damage or ingress that could compromise the IP55 protection. Replace the device if it fails to trip on test or shows signs of wear.
