2 Detailed information

Using the COC4 – A01D1 overcurrent protection relay as a typical example, the following explains how to operate

this type of relay. The item numbers and details depend on model. See the section of “Operational procedure” of

the instruction manual of the model.

In this section, the lamp status of the indicator LEDs are shown according to the following rule using symbols:
