Detection of main contact welding makes it possible to
construct a safety circuit.
• Designed so that Form A contact and Form B contact will
not close at the same time.
• When Form A contact welded, Form B contact gap of at
least 0.5 mm
.020 inch
is maintained.
* Form B contact, when used to monitor the condition of Form A contact, can be
used exclusively as an auxiliary contact.

4. Reduced coil holding voltage contributes to saving
energy of equipment
The coil holding voltage can be reduced up to 30%V of the
nominal coil voltage. This equals to operating power of
approximately 170 mW, which contributes equipment energy
savings.
* Coil holding voltage is the coil voltage after 100 ms from the applied nominal coil
voltage.

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
±1.2×50μs
according to JEC-212-1981
*3. Coil holding voltage is the coil voltage after 100 ms from the applied nominal coil voltage.
*4. Release time will lengthen if a diode, etc., is connected in parallel to the coil. Be sure to verify operation under actual conditions.
*5. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*6. Regarding Form B contact, only the 2 Form A 1 Form B type applies.
