40A 4 Pole 30mA Type B 10KA Residual Current RCD Circuit Breaker
What are RCDs?
Residual Current Devices (RCDs) are safety switching devices. They are designed to provide safety for three types of protection;
- Fault Protection. Any tripping current dependent on the resistance of the earth path.
- Additional Protection. RCDs not exceeding 30 mA tripping current.
- Fire Protection. A tripping current not exceeding 300 mA.

Circuit Diagram
What are the effects of DC residual fault current on RCDs?
it might be worth thinking about some older models of earth fault
loop impedance testers, which could cause the RCD to operate
unintentionally. To prevent this, some types of earth fault loop
impedance testers imposed a DC current on the AC test current. This
DC current saturated the magnetic core of the RCD preventing it
from tripping under the test condition.
Where equipment produces an element of residual DC, for example, variable-speed drives is connected to the electrical installation, the DC component can saturate the magnetic core and effectively blind or locks the RCD. This is known as ‘blinding’ and could either prevent the RCD from operating or reduce the sensitivity resulting in a dangerous situation.
