Eaton Residual current circuit breaker all-current sensitive 4poli

The type B digital RCDs are suitable for all systems, machines, and devices in which DC fault currents can occur, such as:

• DC applications like photovoltaic or uninterruptible power units
• Medical equipment, including X-ray machines
• Test and experimental equipment in laboratories and training rooms
• Frequency converters for motor applications
• Controls for elevators and cranes
• Drives with speed control for rolling machines, lathes, and mills
• Workshops, for example, for the use of welding equipment
• Building industry
• Charging stations for electric cars

Type B detects not only fault currents in the AC and pulse current range but also DC fault currents that can occur in frequency converter controls, photovoltaic systems, and various electronic consumers, even in the household sector, thus significantly increasing safety.
