Benefits

Minimize downtime with direct replacement for ACR relays and RC relays (non z-coil models) in existing case with no wiring changes required.
Reduce inventory with a single BE1-79A relay that replaces multiple ACR types.
Easy setup with a front panel communications interface.
Uncomplicated testing made possible with front panel indicators for relay power and recloser status.
Accurate, repeatable, and reliable operation.
Reduced battery load with low burden power supply.
Available in S1 case for new installations and in S2 and FT-32 cradle for retrofits.
Easily perform in-case system and device tests using test paddles.
