Max. Operating speed
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. Response time is the time after the coil voltage turns off until the time when “a” contact turns off.
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
