J SW3-1 SW3-1 selects the system operating frequency. Opening SW3-1
(OFF) selects 60 hertz operation. Closing SW3-1 (ON) selects 50
hertz operation.
SW3-2 SW3-2 selects additional delay for the instantaneous element.
Closing SW3-2 (ON) provides an additional instantaneous delay of
0.1 seconds.
SW3-3
Closing SW3-3 (ON) provides an additional instantaneous delay of
0.2 seconds. Closing both SW3-2 (ON) and SW3-3 (ON) provides
an additional instantaneous delay of 0.3 seconds.
100 Series Relays
Opening SW3-3 (OFF) selects ABB type curves (refer to Table 1-
3.) Closing SW3-3 (ON) selects GE IAC type curves (refer to
Table 1-4).

SW3-4 SW3-4 provides selection of either instantaneous or integrating
reset characteristics. Closing SW3-4 (ON) selects integrating reset
characteristics. Opening SW3-4 (OFF) selects instantaneous reset
characteristics. See Section 1, General Information,

Jumper E2 to E1A to close the auxiliary contact with the timed (51)
trip. This jumper is yellow and factory installed to close the
auxiliary output contacts with the timed trip.
Jumper E3 to E1B to close the auxiliary contact with the
instantaneous (50) trip. This jumper is blue and factory installed to
close the auxiliary output contacts with the instantaneous trip.
Users with BE1-50/51B unit revisions Q, R, and S in 100 series
relays and unit revisions H and previous in 200 series relays, refer
to Section 6 for the location of the auxiliary output jumper
terminations and the location of SW3. (Note: In all previous
revisions, the reference designator for SW3 was SW8.)
