Important Information Regarding Circuit Breaker Electrical Standard

Festool dust extractors are fitted with a circuit breaker for safety when a connected load of 1200 watts is exceeded.

Some tools that draw higher wattage can trigger the circuit breaker and if initiated requires the reset button above the socket to be pushed in and reset.

When requiring to use larger wattage tools with dust extraction it is recommended the tool is operated off a separate outlet and a Bluetooth system can then be used to switch the dust extractor on and off as required.

When using tools it is recommended you always use the correct consumable for best results as even lower wattage tools can trip the circuit breaker if the system isn’t matched to the application. (e.g.: saw blade not matched to material)

Integrated Bluetooth® technology

Automatically switch on your CT MIDI extractor via remote control or the Bluetooth® battery pack. No retrofitting required. See how here.
