- Provide break both at sine alternating and direct pulse differential current (type A)
- Has built-in overcurrents protectors, provide automatic switch-off at 1.45 In overloads within 1 hour and at 10 In short circuit currents within 0.1 s.
- Able to function at ultimate range of supply line voltages from 110 up to 264V.
- Tolerable range of working temperatures is from -45 ... +55°C.
- Keeping of sensitivity at a repeated earthing of neutral main conductor.
- Possibility of connection of both copper and aluminium conductors.
- Resistant to electromagnetic attacks.
- Cut down lightning and switching impulse voltages within the limit of 2000V at current impulses up to 4500A.
- Light indication of voltage presence in power supply circuit.
- Integrated thermal protection (optional). The device disconnects a protected line from the supply- line when temperature in the RCD zone reaches 100+10°C.
- Temporal overvoltage protection. When voltage increases up to the preset limit (from 265 up to 320V - in accordance with the order) the device is disconnected automatically.
- Possibility of remote disconnection of the device (optional) by an external make contact.
- Have modifications without break time lag - of general type, and with time lag - S type
