SPECIFICATIONS
Current Sensing
BE1-32R and -32 O/U Directional Power Relays are designed for use with five amperes nominal (50/60
HZ) system current transformer secondaries. The input sensing current transformers within the relay are
rated as follows.

See Section 3, Functional Description, Current Sensing for sensing input range
1, 4, and 7 burden considerations.
Voltage Sensing
Voltage signals are provided by the secondary windings of standard potential transformers (100/200, 50
Hz or 120/240, 60 Hz).
Continuous Voltage Rating:
150% of nominal
Burden:
<1 VA
Targets
Electronically latched, manually reset target indicators are optionally available to indicate that a trip output
contact has been energized. Either internally operated or current operated targets may be selected.
Internally operated targets should be selected if the relay has normally closed output contacts.
Current Operated Targets
Minimum Required Current:
200 mA
Continuous Rating:
3 A
2 Minute Rating:
7 A
1 Second Rating:
30 A
