Installation pitch and output switching capacity (reference values)

The relation between the installation pitch and the load current is shown in the following graph. (Except for the H3DK-GE) If Timer is used under load conditions that exceed the specified values, the temperature inside the Timer will increase, reducing the life expectancy of internal parts.

Testing method

Tested Timer: H3DK-F
Applied voltage: 240 VAC
