Operating Procedures

■ Operation, Setting, and Indication

Based on the current value of the motor to be used, perform the setting of each item of the K2CM Motor Protective Relay.

List of Current Settings (when using a 200-VAC motor)

*

The squares (

@) represent the symbols defined under Model Number Legend.

**

The rated current is the current at full load.

*** Supply: Low-voltage 3-phase basket type inductive motor, full-load characteristics of 200 VAC, 4-pole, totally-enclosed.

Note: When using a large-capacity or high-voltage motor whose capacity is 45 kW or more, calculate the rated current/alternating current ratio by

converting with the alternating current ratio of the external current transformer.
