Delays 64, 65 and 66
Delays 64, 65 and 66 are the latest 50/60Hz delays with short, medium
and long trip times respectively. The patented protector design
provides both increased tolerance to high inrush induced nuisance
tripping and longer trip times at 600 percent. These delays are
ideally suited for applications where thermal devices are presently
used, such as motor protection or where short duration, high inrush
currents are experienced. As shown in a typical motor start-up
curve, the delay 66 will provide locked rotor and overload
protection. Nuisance tripping is avoided since acceptable short
periods of overload will not trip the protector.
