BE1-50/51B-235/-236 General Information

9252000898 Rev B

Harmonic Rejection
Rejection of odd and even harmonics is illustrated in Figure 1-5.

Figure 1-5. Harmonic Rejection

Target Indicators
A gravity-latched, manually-reset, current-operated target indicator is provided for the time-overcurrent

(51) trip output and the instantaneous overcurrent A (50-A) trip output. A target indicator is not provided

for the 50-B trip output. The level of trip circuit current required to operate each target is individually

controlled by a circuit board jumper. See Section 2, Controls and Indicators for jumper locations and

function assignments

Jumper Position—Pins 1 and 2:

0.9 to 2.25 A ∗

Minimum Operating Current

Jumper Position—Pins 2 and 3:

80 mA to 200 mA ∗

Minimum operating current values. See Output Contacts for the maximum acceptable levels of

trip circuit currents.

Output Contacts
Output contacts are surge protected and rated as follows.

120/240 Vac:

Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3

amperes continuously, and break 5 amperes.

Resistive Ratings

125/250 Vdc:

Make 30 amperes for 0.2 seconds, carry 7 amperes for 2 minutes, 3

amperes continuously, and break 0.3 ampere.

120/240 Vac, 125/250 Vdc:

Make and carry 30 amperes for 0.2 seconds, carry 7 amperes for 2

minutes, 3 amperes continuously, and break 0.3 ampere. (L/R = 0.04).
