Residual current circuit breakers are currently the most effective protection against electric shock by preventing dangerous touch voltages on the housings of electrical tools and machines. Short-circuit residual current circuit breakers should be used where unwanted trips due to current pulses occur.

Such cases occur, for example:

• in installations with a large group of fluorescent lamps,
• in long cables,
• in x-ray equipment,
• in heating devices with large surfaces,
• when starting large electric motors, transformers, etc.
