Relationship between the mounting interval of 2 or more H3DK units and the output switching capacity (reference value)
See the figure below for the relationship between the mounting interval and the load current.
Note that using the timer under higher load conditions may shorten the lifespan of internal components due to temperature rise inside the timer.

Cautions
- * There is a risk of ignition or explosion due to arcing or heat generation in the relay caused by opening and closing. Do not use in an atmosphere of flammable or explosive gases.
- * The H3DK series has a power supply transformer-less system. Note that you may get an electric shock if you touch the input terminal while the power supply is applied.
- * The inrush current differs depending on the type of load, which affects the opening and closing frequency of the contact and the number of times it is used. Check the inrush current together with the rated current, and design the circuit with a margin.
- * The lifespan of the output relay varies greatly depending on the switching capacity and switching conditions, so be sure to use it within the rated load and the number of electrical lifespan cycles, taking into consideration the actual usage conditions. If it is used beyond its lifespan, contact welding or burnout may occur. Be sure to use the load current below the rated value. When using a heater, etc., be sure to use a thermo switch in the load circuit.
- * Do not remove the outer case.
- * Mild electric shock, fire, and equipment failure may occur in rare cases. Do not disassemble, modify, repair, or touch the inside.
- *For product information other than the above, refer to the catalog.
