1-6 BE1-50/51M - General Information
INST PICKUP
Accuracy
(1 Ampere Unit) ±2% ±5 milliamperes at or above 0.2 ampere settings.
(5 Ampere Unit) ±2% ±25 milliamperes at or above 1.0 ampere settings.
Frequency Response
A change of ±5 hertz from the nominal 50/60 hertz current causes less
than 0.5% change in the current required for pickup.
INST Transient Response
Less than 10% overreach with system time constants up to 40 milliseconds
Burden
Burden is non-linear. (Figure 1-3 illustrates the device burden.)
(1 Ampere Unit) At 0.1 amperes, Z = 120 ohms. At 1.0 ampere, Z = 5 ohms.
(5 Ampere Unit) At 0.5 amperes, Z = 4.8 ohms. At 5.0 amperes, Z = 0.2 ohms.
U.L. Recognition
U.L. recognized per Standard 508, U.L. File Number E97033. Note:
Output contacts are not U.L. recognized for voltages greater than 250 V.
C.S.A. Certification
C.S.A. certified per Standard CAN/CSA-C22.2 Number 14-M91, C.S.A. File
Number LR23131-103s. Note: Output contacts are not C.S.A. certified for
voltages greater than 250 V.
