Table I.2 Specifications: Universal Adapter
Specification Values
Closing At normal pressure, the time from energizing of the pilot valve coil
to contact touch is 7.0 to 7.25 cycles (117 to 121 ms)
Opening Contact Velocity The average contact velocity measured between 1" and 2½" from
the full closed position is 26 to 30 f/s.
Opening Time • Control voltage at the nominal value
• The time from energizing the trip coils to main contact part is 1.30
cycles or less (2 ms)
• Contact travel at .5 of a cycle after contact part is a minimum of
3.4" from the fully closed position
• The contact travel at .9 of a cycle after contact part is less than
5.3" from the fully closed position
Close to Open Operation On a close to open operation the auxiliary switch will energize the
trip coil at contact touch
± .15 cycle (2.5 ms)
Synchronizing Time • Maximum spread of the three poles on closing .25 cycles (4 ms)
• Maximum spread of the three poles on opening contact part
.15 cycles (2.5 ms)
