2.7 W
Y (midrange)
48 Vdc 24 to 150 Vdc 2.5 W
125 Vdc 24 to 150 Vdc 2.8 W
Z (high range)
250 Vdc 68 to 280 Vdc 3.0 W
240 Vac 90 to 270 Vac 19.7 VA
∗ Type L power supply initially requires 14 Vdc to begin operating. Once operating, the input voltage may
be reduced to 12 Vdc and operation will continue.
Target Indicators
Electronically latched, manually reset target indicators indicate closure of the trip output contacts. Either
internally operated or current operated targets may be specified.
Current Operated Targets
Minimum Rating: 200 mA flowing through the trip circuit
Continuous Rating: 3 A
1 Second Rating: 30 A
2 Minute Rating: 7 A
Type Tests
Shock: Withstands 15 G in each of three mutually perpendicular planes
without structural damage or performance degradation.
Vibration: Withstands 2 G in each of three mutually perpendicular planes,
swept over the range of 10 to 500 Hz for a total of six sweeps, 15
minutes each sweep, without structural damage or degradation of
performance.
Isolation: 1,500 Vac at 60 Hz for one minute in accordance with IEC 255-5 and
ANSI/IEEE C37.90-1989 (Dielectric Test)..
Radio Frequency Interference: Field tested using a five-watt, hand-held transceiver operating at
random frequencies centered around 144 megahertz and 440
megahertz, with the antenna located six inches from the relay in both
horizontal and vertical planes.
Surge Withstand Capability: Qualified to IEEE C37.90.1-1989, Standard Surge Withstand
Capability (SWC) Tests for Protective Relays and Relay Systems.
