Target Indicators
A gravity-latched, manually-reset, current-operated target indicator is provided for the time-overcurrent
(51) trip output and the instantaneous overcurrent (50) trip output. The level of trip circuit current required
to operate each target is individually controlled by a circuit board jumper. See the Controls and Indicators
chapter for jumper locations and function assignments
Target Operate Current
Jumper Position—Pins 1 and 2: Must operate ≥ 2.25 A; must not operate < 900 mA.*
Jumper Position—Pins 2 and 3: Must operate ≥ 200 mA; must not operate < 80 mA.*
∗ See Output Contacts for the maximum acceptable levels of trip circuit currents.
Output Contacts
Output contacts are surge protected and rated as follows.
Resistive Ratings
120/240 Vac: Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3
amperes continuously, and break 5 amperes.
125/250 Vdc: Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3
amperes continuously, and break 0.3 ampere.
Inductive Ratings
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).
