2) 3a1b Type
If the form “b” contact (No. 3) welds, the armature becomes non-operational, the contact gaps at the three form “a” contacts are
maintained at greater than 0.5 mm
When the form “a” contacts (No. 1, 2, or 4) weld, the armature remains in a non-returned state and the contact gap at the single form
“b” contact is maintained at greater than 0.5 mm
The table below shows the state of the other contacts when the current through the welded form “a” contact is 0 V and the rated
voltage is applied through the form “b” contact.
