2. Specifications
Notes:
*1.This value can change due to the switching fr equency , environmental cond itions, and desired reliability level, therefor e it is recommended to check this with the actual load.
*2.The upper operation ambie nt temperature limit is the maximum temperature that can satisfy the coil temperature rise value. R efer to “6. Usage, Storage and Transport
Conditions“ in AMBIENT ENVIRONMENT section in Relay Technical Information.
Please inquire if you will be using the relay in a high temperature atmosphere (110C 230F).
*3.Depends on connection cond itions. Also, this does not guarantee repeated switching. We recommend that you conf irm operation under actual conditions.
If the relay is used continuously f or long periods of time with coils on both side s in an ene rgized co ndition, breakdo wn might occur due to abn ormal heating depending on
the carrying condition. Therefore, please inquire when using with a circuit that causes an energized condition on both sides simultaneously.
