Why are There Binding Posts on the Direct Current Input Terminals?

What Is Open Circuit Protection?

This is to prevent an open current circuit. Among non-Japanese power meters, there are products that also use safety terminals for current terminals. Safety terminals can be said to be safe because the terminal is not exposed in the event that wiring becomes disconnected, but the wiring itself is easily disconnected.

What is the Risk of an Open Circuit?

If the current circuit can easily become an open circuit, this represents a safety hazard. Therefore, with our power meters, wiring is fastened with binding posts terminals ensuring that they cannot be easily pulled out, and by covering the terminals with a protective cover they cannot be directly touched. Also, when you consider measurements of large currents with a power meter, a common safety terminal can handle currents of about 20 A, which makes them inappropriate for large current measurement. The types of input terminal used may change depending on current customer demand and technical trends.

Protection Current Transformers

A protection current transformer reduces the power system's primary alternating current (AC).
