Motor Protective Relay
K2CM
Solid-state Relay Enables Choice of Three
Operating Functions (Overcurrent, Open-
phase, and Reverse-phase)
• Protects 3-phase induction motors and their loads from dam-
age.
• Selection and combination of operating functions from overcur-
rent, open-phase, and reverse-phase.
• Circuit and output relay operation can be checked by just oper-
ating 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.
