Product Description

PK2 is a single-phase surge arrester type 3 according to EN 61643-11. Designed for universal application for the protection of all kinds of electrical devices connected to the network nn against impulse surge effects.

It is suitable for TN-S and TN-C. On request, the customer can request this type for other than operating voltage 230V/50Hz. Failure varistor is indicated by sliding the red slider disc mechanical thermal fuse, react to varistors overheating above the temperature of 120 º C.

Single-phase SPD Class III combination-type systems for networks with grounding-type TN-S, TT. U N = 24, 60, 230 V.
     The device series Pk2 (DS) correspond to the SPD Class III, Division according to GOST R 51992-2002 (IEC 61643-1-98). Installed after the SPD Class II within 2 - 3 lightning protection zones (in accordance with IEC 1312-1, IEC 62305 and CO-153-34.21.122-2003) in the vicinity of the protected equipment. Are designed to protect end-users from the residual surge voltage surges.
PK2 (DS) , TU 3428-002-79740390-2007 - a series of SPD Class III on the basis of zinc oxide varistors and gas-filled spark gap.
• Designed to protect equipment in chains L / N, L / PE, N / PE from residual surge voltage surges.
• Available at the nominal operating voltage U N = 24, 60, 230 (AC / DC). 
• Visual inspection of the working condition of the SPD is performed using the red indicator. In good condition indicator drowned in an emergency - advanced. 
• For remote control Pk2 DS cnabzheny additional "dry" contacts remote alarm. 
•  The protected equipment should be placed at a distance of no more than 10-15 m from the SPD Class III.Subject to the rules of the amplitude of the voltage on the protected equipment will not exceed 900 V.

    Pk2 (DS) DC networks are designed to protect the DC system grounding type TN-S system A, in accordance with GOST R 50571.2-94 (IEC 364-3-93), where "-" is grounded. "+" Is connected to Klem "C", "-" is connected to terminal "D". There electrical wherein "+" is grounded in this case, "+" is connected to terminal "D", and "-" to the terminal "C . "
    For measurements made in the electrical installation when the measurement technique provides high voltage test (for example, testing of insulation resistance) must be disconnected from the electrical surge protection. Failure to do so will lead to a distortion of results or, in the worst case, the output of the device failure.

Pk2 is a single-phase surge arrester type 3 according to EN 61643-11 suitable for TNS and TNC systems. It is designed for universal application for protection of all electrical appliances connected to L.V. supply system against impulse surge effects. It is possible to supply this arrester for different nominal voltage (different from 230V/50Hz) on a special demand. The function failure of varistor is indicated by target disconnection of mechanical thermal fuse which react to varistor overheating above c. 120°C.
