9137200997 Rev D BE1-51 General Information 1-1
SECTION 1 •GENERAL INFORMATION
DESCRIPTION
BE1-51 Time Overcurrent Relays are microprocessor-based devices that monitor the magnitude of single-
phase, two-phase-and-neutral, or three-phase-and-neutral ac current to provide accurate time overcurrent
and instantaneous overcurrent protection for 50 hertz or 60 hertz power systems.
STANDARD FEATURES
Time Overcurrent Functions
Time overcurrent elements pick up over a range of 0.1 to 0.8 amperes, 0.3 to 2.4 amperes, 0.5 to 4.0
amperes, 1.5 to 12.0 amperes, 0.1 to 2.4 amperes, or 0.5 to 12.0 amperes and provide an adjustable time
delay that is proportional to the overcurrent. Time delay is initiated when the sensed current exceeds the
pickup point. When the current drops below the pickup point, the timing circuit is reset immediately. At
reset, the output contacts, if operated, are restored to normal.
Adjustment of the overcurrent pickup point is provided by controls on the relay front panel. Time delay is a
function of the characteristic curve that has been selected. Time delay is settable from 00 to 99 on the
TIME DIAL thumbwheel switch located on the front panel. Curve type is selected either as an option or, in
some models, is switch selectable.
Sixty-nine characteristic curves and three timing options are available. They are:
Characteristic curves:
•Seven inverse time
•Nine I2t
•Seven inverse time with extended timing range
•Nine I2t with extended timing range
•Five British Standard 142 (E curves)
•Seven integrating inverse time
•Nine integrating I2t
•Seven integrating inverse time with extended timing range
•Nine integrating I2t with extended timing range
Timing option Z1 (switch selectable - 16 position) B and C curves:
•Seven inverse time
•Nine I2t
Timing option Z1 with option 2-D or 2-E (switch selectable - 16 position) B and C curves:
•Seven inverse time with extended timing range
•Nine I2t with extended timing range
Timing option Z2 (switch selectable - 16 position) B and E (British Standard 142) curves:
•Seven inverse time
•One I2t
•Five British Standard (BS) 142 (E curves)
Timing option Z2 with option 2-D or 2-E (switch selectable - 16 position) B and E (BS142) curves:
•Seven inverse time with extended timing range
•One I2t with extended timing range
•Five British Standard 142 (E curves)
Timing option Z3 (switch selectable - 16 position) integrating B and C curves:
•Seven integrating inverse time
•Nine integrating I2t
Timing option Z3 with option 2-D or 2-E (switch selectable - 16 position) integrating extended B and C
curves:
•Seven integrating inverse time with extended timing range
•Nine integrating I2t with extended timing range

1-2 BE1-51 General Information 9137200997 Rev D
Characteristic curves are shown by the graphs in Appendix A, Time Overcurrent Characteristic Curves.
Note that each graph (i.e. function) consists of a set of representative curves. Each curve (as well as any
between-curve interpolation) is selectable by the front panel TIME DIAL using a two-digit destination from
00 to 99. Because of space limitations, each graph shows only 14 of the 100 possible selections.
Non-Integrating Timing
Timing options Z1 and Z2 and the characteristic curves available with those options use non-integrating
timing. Non-integrating timing is accomplished by timing at a gate that is not solely dependent on the
magnitude of the applied multiple of pickup current. The time-out value is calculated based on the type of
time curve characteristic selected, time dial setting, and the magnitude of the applied multiple of pickup
current. The time-out value is continuously updated during the timing cycle. When pickup is exceeded, a
timer is initiated. When the timer elapsed time exceeds the calculated time-out value, a time trip output
signal is generated.
This type of non-integrating time delay characteristic exhibits a dynamic characteristic that is immediately
responsive to changes of the applied multiple of pickup current.
Integrating Timing
Timing option Z3 and the characteristic curves available for that option uses integrating timing. Integrating
timing is accomplished by summing time increments that are based on the magnitude of the applied
multiple of pickup current, the time curve characteristic selected, and the time dial value. These time
increments are summed until a predetermined value is exceeded, then a time trip output signal is
generated.
This type of integrating time delay characteristic simulates the operating characteristics of an
electromechanical overcurrent relay.
Built-In Test
A built-in test (BIT) switch mounted on the Logic Board provides diagnostic troubleshooting and
calibration.
OPTIONS
Timing
An extended timing option multiplies by approximately 5.7, the standard time delays. The resulting curves
are shown following the standard curves in Appendix A - e.g., Figure A-1 is timing type B1 and Figure A-2
is the timing type B1 with extended timing range.
When timing option Z1, Z2, or Z3 is specified, a printed circuit board mounted selector switch allows a
choice of up to sixteen different time overcurrent functions. Timing option Z1 or Z3 may be further
specified as standard or extended time, depending upon option 2 selection.
Neutral Defeat
When neutral defeat is specified, a front panel switch allows neutral current sensing to be disabled. This
function permits the user to energize desired circuits and not trip because of imbalanced current in the
neutral circuit. After the circuits are balanced, the neutral defeat function can be switched off and neutral
current sensing protection is provided.
Sensing Input Type
When single-phase, two-phase-and-neutral, three-phase, or three-phase-and-neutral sensing has been
specified, the front panel TAP selector and the front panel TAP CAL control set the pickup point for all
phases. An independent front panel TAP (NEUTRAL) selector and front panel CAL (NEUTRAL) control
set the neutral pickup point. In addition, for three-phase-and-neutral sensing units, one of the seven
sensing input range combinations must be specified.
Sensing Input Range
For three-phase-and-neutral sensing units, input ranges are:
•0.5 to 4.0 amperes (phase and neutral)
•1.5 to 12 amperes (phase) and 0.5 to 4.0 amperes (neutral)
Courtesy of NationalSwitchgear.com

9137200997 Rev D BE1-51 General Information 1-3
•0.5 to 4 amperes (phase) and 1.5 to 12 amperes (neutral)
•1.5 to 12 amperes (phase and neutral)
•0.1 to 0.8 amperes (phase and neutral)
•0.3 to 2.4 amperes (phase) and 0.1 to 0.8 amperes (neutral)
•0.3 to 2.4 amperes (phase and neutral)
For all other units, two ranges are available. They are 0.5 to 12 amperes and 0.1 to 2.4 amperes.
Power Supply
Five power supply options are available. They are:
•24 Vdc
•48 Vdc
•125 Vdc and 100/125 Vac
•48 Vdc or 125 Vdc and 100/125 Vac
•250 Vdc and 240 Vac
Targets
Single-phase relays have two function targets that indicate when the time delay or instantaneous
element(s) have operated. On multiple phase relays, additional targets indicate which phase or neutral
element(s) operated.
Function targets may be specified as either internally operated or current operated by a minimum of 0.2
amperes through the output trip circuit. When current operated, the output circuit must be limited to 30
amperes for 0.2 seconds, 7 amperes for 2 minutes, and 3 amperes continuously.
Outputs
Optional normally opened, normally closed, or SPDT auxiliary output contacts may be selected. Contacts
actuate when the output relay is energized. Internally operated front panel mounted targets, and front
panel targets operated by the dc current in the output circuit are available for the time overcurrent and
instantaneous overcurrent functions. Optional front panel mounted PUSH-TO-ENERGIZE-OUTPUT
pushbuttons allow direct actuation of each output relay for external circuit testing.
Instantaneous Outputs
One or two instantaneous overcurrent outputs are optionally available. Each is adjustable up to 40 times
the time overcurrent pickup point. When the sensed current exceeds the instantaneous overcurrent
pickup point, an output relay is energized. An independent front panel control (INST 1 or INST 2) adjusts
the pickup point for each optional output. If more than one phase is applied to the relay, the instantaneous
pickup point will be the same for all phases. If neutral current is sensed, a front panel INST 1 (NEUTRAL)
provides adjustment of the neutral pickup point. Instantaneous overcurrent elements are not voltage
controlled.
Packaging
Each relay is mounted in a drawout cradle and enclosed in a standard utility style case with either semi-
flush or projection mounting (depending upon case style selected). Circuit components are accessed by
removing the individual printed circuit boards from the relay cradle. Use an extender card (Basler Electric
part number: 9165500199) to test and troubleshoot the relay. An available test plug (Basler Electric part
number: 10095 or G.E. part number 12XLA12A1) allows the relay to be tested in place without disturbing
external control circuit wiring.
MODEL AND STYLE NUMBER DESCRIPTION
Electrical characteristics and operational features included in a particular style of the BE1-51 Time
Overcurrent Relay are defined by a combination of letters and numbers that make up its style number.
The model number, together with the style number, describes the options included in a specific device,
and appears on the front panel, drawout cradle, and inside the case assembly. Upon receipt of a relay, be
sure to check the style number against the requisition and the packing list to ensure that they agree.
