KPv-600 series contactors are designed for switching power circuits under heavy duty cycles. KPv-600 series contactors are designed with one main making contact and are used in DC power circuits with a voltage of 220V (440V). Contactors for currents of 250A and 630A with infrequent operations - at voltages up to 600V. The permissible number of operations depending on the load type for KPv-600 is up to 1200 per hour. KPv-600 series contactors are primarily intended for controlling DC motors and are used as line contactors, reversing contactors, acceleration contactors, etc.
