1-6 BE1-87G - General Information
Pickup Accuracy
(1 Ampere) For I
R
1 ampere, ±5% of the operate pickup characteristic or 25
milliamperes whichever is greater. Actual operating characteristics are
shown in graph format in Section 5,
Testing And Setting the relay.
For I
R
1 amperes, up to a maximum of 4 amperes, ±8% of the operate
pickup characteristic or 150 milliamperes, whichever is greater. Actual
operating characteristics for pickup values between 1 and 4 amperes are
shown in graph format in Section 5,
Testing And Setting the relay.
Dropout Greater than 90% of operate characteristic.
Timing Less than 30 milliseconds at 10 times pickup setting; 70 milliseconds
maximum. See Section 5,
Testing And Setting the relay, for the pickup
response timing curve.
Power Supply Power for the internal circuitry may be derived from ac or dc external power
sources as indicated in Table 1-1.

+ Type L power supplies may initially require 14 Vdc to begin operating. Once
operating, the voltage may be reduced to 12 Vdc and operation will continue.
Output Contacts Output contacts are rated as follows.
Resistive:
120/240 Vac Make and carry 30 amperes for 0.2 seconds, carry 7 amperes
continuously, and break 7 amperes.
125/250 Vdc Make and carry 30 amperes for 0.2 seconds, carry 7 amperes
continuously, and break 0.3 ampere.
Inductive:
120/240 Vac, Make and break 0.1 A (L/R = 0.04).
125/250 Vdc Make and break 0.1 A (L/R = 0.04).
Targets Magnetically latched, manually reset target indicators may be optionally
selected as either internally operated or current operated. Current
operated targets require a minimum of 0.2 ampere through the output trip
circuit and are rated at 30 amperes for 1 second, 7 amperes for 2 minutes,
and 3 amperes continuously.
