Trip Class

Application Description

5

Small fractional horsepower motors where acceleration times are almost
instantaneous or where extremely quick trip times are required.

10

(Fast Trip) Hermetic refrigerant motors, compressors, submersible pumps and
general-purpose motors that reach rated speed in less than 4 seconds.

15 

Specialized 

applications

20

(Standard Trip) Most NEMA-rated, general-purpose motors will be protected by
this setting.

30

(Slow Trip) Motors with long acceleration times (>10 seconds) or high inertia
loads.

J prefix

Programming any of the trip classes with the J Prefix will enable jam protection.
This additional protection is enabled 1 minute after the motor starts and
provides a 2-second trip time for motors exceeding 400% of the OC setting,
regardless  of trip class.
