Motor Protective Relay K2CM CSM K2CM DS E 6 3 Solid-state Relay Enables Choice of Three Operating Functions (Overcurrent, Open- phase, and Reverse-phase) Protects 3-phase induction motors and their loads from damage. Selection and combination of operating functions from overcur- rent, open-phase, and reverse-phase. Circuit and output relay operation can be checked by just operat- ing the test button. The set time value can be checked easily because operation time is indicated from the start of operation. Space-saving, integrated construction. Note: If the K2CM is used with an inverter, the operating conditions will depend on the load wiring length, inverter carrier frequency, basic frequency, and load conditions. Error will occur in the operating values of the overload elements. It is recommended to test operation before using the K2CM. Model Number Structure Model Number Legend K2CM- - 12 3 4 5 6 1. Model 5.
