Type B circuit breaker is used in photovoltaic devices, in households, as protection for electric car chargers and for industrial power distribution for special purposes (direct current). When designing and installing electrical installations, electrical loads can generate DC residual current in the event of a fault, a separate electrical circuit must be assigned.
Type B RCD is intended for use in applications with frequency converters, in medical devices, UPS, mobile installations, in elevators and more. Type B RCDs are not intended for use in DC systems and networks with operating frequencies other than 50 or 60 Hz. For type B, conditions are defined for frequencies up to 1 kHz.
