SECTION 1 • GENERAL INFORMATION
Description
The BE1-79A Reclosing Relay is an economical, microprocessor-based relay that automatically recloses
circuit breakers that have been tripped by protective relays or other devices in power transmission and
distribution systems. The BE1-79A offers true "plug and play" convenience; it can be installed in an
existing GE type S2 case with no wiring changes required. General Electric type ACR11A, ACR11B,
ACR11C, ACR11E, and ACR11F reclosing relays can be directly replaced by the BE1-79A-100 or BE179A-101. The BE1-79A-200 and BE1-79A-201 are available in a shorter cradle that fits in a Basler S1
case for new installations.
Table 1-1 lists the case style and special features of each version of the BE1-79A.

Features
BE1-79A Multiple Shot Reclosing Relays have the following standard features:
• Rugged construction in a steel, draw-out case
• A maximum of four automatic reclosures
• A maximum of four automatic resets
• Lockout function
• Selectable instantaneous or delayed first reclosure
• Selectable internal or external instantaneous jumper
• Selectable normally closed or normally open RS output contact
• Selectable Relay Fail or Lockout and Relay Fail output contact
• Selectable contact sensing voltage range
Controls and Indicators
The front panel has indicators to verify relay power and recloser status. A Reset switch is provided to
restore the relay to the reset mode by clearing a reclosing sequence or a lockout condition. The left side
of the relay cradle has switches (S1, S2, and S3) to configure the relay for either ACR11A or ACR11B
operation. The right side of the cradle has a switch (S4) to select either an internal or an external jumper
for an instantaneous, first reclose. The right side of the cradle also has a switch (S5) to select either
normally open or normally closed operation of the RS contact.
Communication
All relay settings are read or changed through the serial port located on the front panel. The BE1-79A
uses ASCII protocol.
Power Holdup Circuit
The BE1-79A is available with an optional, internal, power holdup circuit. This circuitry maintains the
output contacts for a minimum of 40 cycles after nominal operating power is removed from relay terminals
5 and 6.
Primary Application
The BE1-79A automatically recloses circuit breakers that have been tripped by protective relays or other
devices in power transmission and distribution systems.
Over 90% of faults occurring on overhead lines may be cleared by momentarily de-energizing the line.
Once the circuit breaker has been opened to de-energize the line, the BE1-79A provides a reliable
automatic reclosure. The advantages are:
•Improved service continuity—returns the line to service quickly, preserving line integrity, and
minimizing outage effects on critical loads.
• System stability—prevents disjointing of the system grid.
• Higher line availability—decreases likelihood of permanent loss of line.
