2. Specifications
* Specifications will vary with foreign standards certification ratings.
Notes:
*1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual
load.
*2. Wave is standard shock voltage of 1.250s according to JEC-212-1981
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport
Conditions“ in AMBIENT ENVIRONMENT section in Relay Technical Information.
