GENERAL INFORMATION
SPECIFICATIONS
Voltage Sensing
Nominally rated at 50/60 Hz, (120/240 V or 100/200 V) with a
maximum continuous voltage rating of 360 V (120 V nominal )
or 480 V (240 V nominal ) at a burden less than 1 VA per
phase. Frequency range is from 40 to 70 Hz.

† Type L power supply may require 14 Vdc to begin operating.
Once operating, the voltage may be reduced to 12 Vdc.
Target Indicators
Magnetically latching, manually reset target indicators are
optionally available to indicate that a trip output contact has
energized. Either internally operated or current operated targets
may be selected. Current operated targets require a minimum of
0.2 Adc flowing through the output trip circuit, and are rated at
30 A for 1 second, 7 A for 2 minutes, and 3 A continuously.
Internally operated targets should be selected if the breaker
control circuit is ac powered, or if the relay has normally closed
output contacts.
Output Contacts:
Resistive
Inductive
Output contacts are rated as follows:
120 Vac - make, break, and carry 7 A continuously.
250 Vdc - make and carry 30 A for 0.2 seconds, carry 7 A con-
tinuously, break 0.1 A.
500 Vdc - make and carry 15 A for 0.2 seconds, carry 7 A con-
tinuously, break 0.1 A.
120 Vac, 125 Vdc, 250 Vdc - break 0.1 A (L/R = 0. 04) .
Undervoltage and Overvoltage
Pickup Range
Continuously adjustable over the range of 1 to 40, 55 to 160, or
110 to 320 Vac as defined by the Style Chart. See Section 3,
System Voltages for explanation of pickup ranges.
Undervoltage and Overvoltage
Pickup Accuracy
± 2% or ± 0.5 volts of the pickup setting, whichever is greater.
Dropout Accuracy
± 2% of pickup.
Instantaneous Time Accuracy
Less than 50 ms for a voltage level that exceeds the pickup
setting by 5% or 1 volt, whichever is greater.
Definite Time Range
Adjustable over the range of 0.1 to 9.9 seconds in increments of
0.1 seconds. A setting of 00 designates instantaneous timing.
