3. Compact size and low operating power
W: 30 × L: 36 × H: 40 mm W: 1.181 × L: 1.417 × H: 1.575 inch
Operating power: 1,880 mW (holding power: 170 mW)
Detection of main contact welding makes it possible to
construct a safety circuit.
• Designed so that Form A contact and Form B contact will
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.
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.
