Auxiliary circuit switching devices of KSAM series

KSAM series switching devices of auxiliary circuits are intended for the use as embedded components of auxiliary electric circuits of high-voltage drives: disconnectors, grounding conductors, separators, and short circuiting switches.

Auxiliary circuit switching devices of KSAM series

KSAM type switching devices are designed for switching of auxiliary electric circuits with an alternating current voltage of 380 V and frequency of 50 and 60 Hz as well as direct current voltage of 220 V.

Climatic category of the terminals and terminal blocks is UKhL (temperate and cold weather) and T (tropical weather) (respectively, NF and T according to IEC); placement category is 3 according to GOST 15150.

The switching devices embedded in the shell of IP54 protection rating according to GOST 14254-96 are applicable in the reference conditions for devices of climatic category UKhL and T (respectively, NF and T according to IEC) and placement category of 3 according to GOST 15150.

Examples of the designation of the device when placing an order and in the documents of other products are as follows:

  1. “Switching device KSAM 11-21-11304-UKhL3, according to the Corporate Standard Ts 00212883-015:2014”;
  2. “Switching device KSAM 11-21-11304-T3, export, according to the Corporate Standard Ts 00212883-015:2014”.
