Note: 1. Do not allow the load current to exceed the rated value.
             2. The contact ON/OFF timing is not synchronized. Confirm performance before application.
             3. Once the contacts have been used to switch a load, however, they cannot be used to switch smaller loads. The
                   contact surfaces will become rough once they have been used and contact reliability for smaller loads may be
                   reduced.
*1. Malfunction within 1 ms.
*2. With no icing or condensation.
*3. The degree of protection from the front of the panel.
