Figure 1-5. Harmonic Rejection
Target Indicators
Gravity latched, manually reset targets indicate that current of 0.2 amperes or greater was present in the
trip circuit. Target coil resistance is less than 0.1 ohms and operate time is less than one millisecond. See
Output Contacts for maximum current rating.
Output Contacts
Output contacts are surge protected and rated as follows:
120/240 Vac ............................... Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3
amperes continuously, and break 5 amperes.
Resistive Ratings
125/250 Vdc ............................... Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3
amperes continuously, and break 0.3 ampere.
120/240 Vac, 125/250 Vdc ........ Make and carry 30 amperes for 0.2 seconds, carry 7 amperes for 2
minutes, 3 amperes continuously, and break 0.3 ampere. (L/R = 0.04).
Inductive Ratings
AUX Output Contact
The AUX Output contact can be configured in the field using jumpers to select closing on either timed or
instantaneous trip. The AUX output contact is surge protected and has the same ratings as the output
contacts above.
