Siemens 4-pole Type A RCD, 30 mA, C-tripping curve, 6 kA, 25 A rated current for reliable ground-fault protection in 230/400 V three-phase installations.
Siemens is a global leader in electrical automation and protection technology, with decades of experience manufacturing reliable circuit breakers and residual current devices for residential, commercial, and industrial applications worldwide.
A Type A RCD detects both sinusoidal AC and pulsating DC residual currents, providing protection against electric shock and fire in circuits with electronic loads such as LED drivers, inverters, and washing machines.
The Type C tripping curve means the device trips at 5–10 times the rated current, making it suitable for circuits with moderate inrush currents from inductive loads like motors and transformers without nuisance tripping.
The rated current is 25 A and the rated voltage is 400 V, matching standard three-phase distribution in European installations.
It is a 4-pole device, meaning it simultaneously disconnects all three live conductors plus the neutral, providing complete circuit isolation for safety during maintenance or fault conditions.
The 6 kA short-circuit breaking capacity allows the device to safely interrupt fault currents up to 6,000 amperes, protecting the installation and downstream equipment from damage.
