Advantages

• Compact residual current-controlled circuit breaker construction with the integrated overcurrent protection.
• Rated conditional short-circuit current of 6000A provides for installing AVDT34 as incoming protection switches.
• RCD type A ensures universal shock hazard protection in case of eventual unintentional contact with conducting parts and earth current leakages.
• High electrical wear resistance: not less than 6000 powering cycles.
• Wide range of rated (6, 10, 16, 25 and 32 A) and rated breaking residual currents (10, 30, 100, 300 mA).
• Ergonomic “TEST” button for checking the device’s operation and accuracy of connection.
• Main contacts of 4-polar residual current operated circuit breakers with overcurrent protection AVDT34 are constructed in the way that the neutral pin is closed earlier and broken later that allows preventing electrical imbalance equivalent to a neutral conductor cut-off.
• Possibility to install:
  • universal status contact KDU60;
  • shunt trip RN60.

Design Features

	Compact residual current-controlled circuit breaker construction with the integrated overcurrent protection occupies 4 modules in the board.		Double quenching grid at the arch chute output raises fire safety preventing combustion products from exposing.
	New construction of trip-free release mechanism ensures fast main contacts breaking.		Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection.
	Welding deposition of silver-bearing composite provides for boosting the contact block’s wear-resistance and lowering the transient one.		Main circuit status indicator provides exact information on the contacts status independently from lever position. Rated conditional short-circuit current of 6000A. Boosted range of operating temperatures from –25 to +40° С.
	Arching plate of moving contact is constructed as a smooth curve that substantially facilitates drawing arch into the arch extinguishing chamber.		DIN rail latch with a double fixed position for the convenience of installation.
	Quenching grids with boosted number of plates at each pole provide for more efficient electric arch extinguishing.		Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation.
