The digital FI-protection switch Type B+ are for all systems, machines and devices in which DC fault currents can occur, e.g.:Dc applications such as photovoltaic or uninterruptible units- Medical devices such as x-ray devicesTest and experimental facilities in laboratory and training roomsFrequency converters for motor applicationsControls for lifts and cranesDrives with speed control for rolling machines, rotary benches, mills,…Workshops (for example, for the use of welding devices)- ConstructionCharging stations for electric cars.Type B+: Allstromsensitiver FI switch for applications, in which errors can occur. Not selective, not time-delayed. Protects in the event of all fault current forms. Also meets the requirements of the VDE 0664-400 0664-110 (formerly VDE V) for extended fire protection.This text is machine translated.
