The FI circuit breaker (RCD) is a protection device in electrical installation, which can save life in an emergency. This closes the circuit when an error current is detected within a millisecond to prevent accidents. avoid this. The FI compares the flow and draining current, it detects a deviation, triggers it immediately. The standard DIN VDE 0100-722 sees its own circuit for each charging port of electric vehicles must be protected by an FI switch. This must have a maximum rated differential current of 30 mA. In addition, it requires protection against DC fault currents, these are supplied with the FI switch. Type B with covered. Top features: Detects not only normal AC, but also high-frequency AC and the smallest DC fault currents. High switch-off capacity up to 10 ka. With display window for RCCB errors. With grip safety system to protect against misoperation With protective cover for internal screws for insulation and sealing functions.
