DELAY 61
50/60Hz Delay Curves (typ)
A choice of delays is offered for 50/60Hz applications.
Delay 61 is a short delay for general purpose
applications. Delay 62 is long enough to start certain
types of motors and most transformer and capacitor
loads.

Delay 63 is a long delay for special motor applications.
Delays 64, 65 and 66 are the latest 50/60Hz delays with
short, medium and long trip times respectively. The
patented breaker 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 breaker.

All trip curves and trip currents are specified with the
breaker mounted in the normal vertical position at
ambient temperature of +25°C. For test and
measurement purposes, the breakers should not carry
current prior to application of overload for calibration
test. For other than vertical mount position, consult
factory.
