Safety locks PK(t) high-voltage series

This production is certified by OS "The international standards and systems No. UA1.093.0003154-11 and conforms to requirements of GOST 2213-79, TU U 31.2-37056635-001:2010.

Safety locks the PK(t) high-voltage series are intended for protection of high-voltage power chains of transformers, air and cable networks, alternating current of frequency 50-60gts from overloads and currents of short circuit.

Technical characteristics

Safety locks disconnect without damage currents from rated minimum current of shutdown to rated current of shutdown and belong to the class 2 in accordance with GOST 2213.

At shutdown of currents, amplitude value of tension arising between conclusions of safety locks does not exceed: for safety locks of 6 kV - no more than 15 kV; for safety locks of 10 kV - no more than 25 kV; for safety locks of 35 kV - no more than 85 kV.

Electric durability of isolation of safety locks - in accordance with GOST 1516.1

Cartridges of safety locks of category of placement of U1, U2 and HL1, HL2 - are waterproof.

Safety locks according to characteristics are current-limiting.
