Advantages

• Residual current circuit switch VD1-63 type A is a solid jam-resistant electromechanical UZO capable of ensuring universal electric shock hazard protection in case of eventual unintentional contact with conducting parts of electric installations and preventing fires caused by earth current leakages.
• High electrical wear resistance: not less than 4000 powering cycles.
• Rated short circuit conventional current: 4500 A.
• Silver-bearing depositions on contacts.
• Wide range of rated currents (16, 25, 32, 40, 50 and 63 A) and rated breaking residual currents (10, 30 and 100 mA)
• Notches on terminal clamps provide for lowering thermal losses and boosting the mechanical stability of connection.
• Loads can be connected both to upper and lower clamps.
• Wide range of operating currents for in-services control device (from 110 to 265 V in 2-pole item and from 200 to 460 V in 4-pole one).
• Main contacts of 4-pole residual current circuit switch VD1-63 type A are designed 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.

Design Features

	Ergonomic “TEST” button for checking the device’s operation and accuracy of connection. Rated short circuit current of 4500 A provides for sustaining higher overcurrents than the preceding residual current circuit switch series.		Boosted range of operating temperatures from –25 to +40° С contributes to applying this switch in different climatic zones.
	Free of internal consumption. Preserves working capacity even after a neutral conductor cut-off.		Main circuit status indicator provides exact information on the contacts status independently from lever position.
	Applying special materials in the residual transformer core helped to create residual current circuit switch of A type without using electronic components.		Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection.
	Quenching grids with boosted number of plates at each pole provide for more efficient electric arch extinguishing.		Boosted screw head dimension with a universal crest appropriate bot for cross and flat blade screwdriver helps to facilitate mounting and prevents the screws from falling out during the installation.
	Possibility of double simultaneous connection both with a bus (PIN, FORK) and flexible conductors having up to 50 mm2 in section.		Terminals marking on the casing provides for avoiding mounting faults and sealing of screws connecting the casing – its unauthorised diassembling.
