*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: Coil holding voltage is the coil voltage after 100 ms from the application of rated coil voltage.
*3: If a diode is connected across the coil in parallel, the release time will be delayed.
Check this under actual operating conditions.
*4: For ambient temperature, please read "GUIDELINES FOR RELAY USAGE".
