Electric shock protection
-Overcurrent protection
-Temporary overvoltage protection
-Impulse overvoltage protection
-Cut down Lightning and interconnect impulse voltages
-Fire-safety increasing at additional currents and inadmissible earth leakage currents
-Remote break control
-Diminished overall dimensions
STANDARD COMPLIANCECompliance with IEC61009-1 GB16917-1
PECULIAR FEATURESBuilt-in overvoltage protection with breaking time of not more than 0.5 sec.
Built-in impulse overvoltage protection up to 10 kV with current up to 5 kA.
Built-in terminal clamps for remote break control
Width is equal to the width of 3 unified modules
"T" button color depends on rated breaking differential current value (10 mA white, 30mA grey, 100mA black(brawn), 300mA-blue).
ADVANTAGES
Provide breaking both at sinusoidal AC,and at direct pulsing DC(A type).
Have built-in overcurrents protection type C,provide automatic switch-off at 1.45 In overloads within 1 hour and at 10 In short circuit currents within 0.1s.
Wide range of modifications.
Have modifications without break time lag at differential current operation - S type
Able to function at ultimate phase voltage range of supply lines from 110 up to 264V
Tolerable range of working temperatures is from -25...+55 C.
Keeping of sensitivity at a repeated earthing of neutral main conductor.
Resistant to electromagnetic attacks
Cut down lighting impulse voltages within the limit of 2000V
Possibility of connection of both copper and aluminum conductors
Light indication of voltage presence in power supply circuit
Temporal overvoltage protection from 265V.
