SEL-387E Instruction Manual
Cyclic Capacity (2.5 cycles/second):
24 V 0.75 A L/R = 40 ms
48 V 0.50 A L/R = 40 ms
125 V 0.30 A L/R = 40 ms
250 V 0.20 A L/R = 40 ms
High Current Interrupting Option:
Make: 30A; Carry: 6 A continuous carry at 70°C, 4 A continuous carry at 85°C;
1 s rating: 50 A; MOV protected: 330 Vdc, 130 J;
Pickup time: Less than 5 ms; Dropout time: Less than 8 ms, typical
Breaking Capacity (10000 operations):
24 V 10 A L/R = 40 ms
48 V 10 A L/R = 40 ms
125 V 10 A L/R = 40 ms
250 V 10 A L/R = 20 ms
Cyclic Capacity (4 cycles in 1 second, followed by 2 minutes idle for thermal dissipation):
24 V 10 A L/R = 40 ms
48 V 10 A L/R = 40 ms

Note: Do not use high current interrupting output contacts to switch ac control signals. These outputs
are polarity dependent.
Note: Make per IEEE C37.90-1989; Breaking and Cyclic Capacity per IEC 60255-23
[IEC 255-23]: 1994.
Optoisolated Inputs: 250 Vdc: Pickup 200–300 Vdc; Dropout 150 Vdc
125 Vdc: Pickup 105–150 Vdc; Dropout 75 Vdc
110 Vdc: Pickup 88–132 Vdc; Dropout 66 Vdc
48 Vdc: Pickup 38.4–60 Vdc; Dropout 28.8 Vdc
24 Vdc: Pickup 15.0–30 Vdc
Note: 24, 48, and 125 Vdc optoisolated inputs draw approximately 4 mA of current, 110 Vdc inputs
draw approximately 8 mA of current, and 250 Vdc inputs draw approximately 5 mA of current.
All current ratings are at nominal input voltage.
