Target Indicators
A gravity-latched, manually-reset, current-operated target indicator is provided for the time-overcurrent
(51) trip output and the instantaneous overcurrent A (50-A) trip output. A target indicator is not provided
for the 50-B trip output. The level of trip circuit current required to operate each target is individually
controlled by a circuit board jumper. See Section 2, Controls and Indicators for jumper locations and
function assignments
Jumper Position—Pins 1 and 2: 0.9 to 2.25 A ∗
Minimum Operating Current
Jumper Position—Pins 2 and 3: 80 mA to 200 mA ∗
*
Minimum operating current values. See Output Contacts for the maximum acceptable levels of trip
circuit currents.
Output Contacts
Output contacts are surge protected and rated as follows.
