Eagle Overview

Self-Powered Single Phase Recloser

for up to 27kV

Fused overhead distribution

lateral protection

Utilities generally deploy fuse-blowing or fuse-

saving protection techniques for lateral circuit

protection. Fuse based lateral circuit protection

has major drawbacks in terms of the outages

experienced by customers for transient faults.

Since majority of the faults on overhead

distribution circuits are transient, the outages,

service calls, dispatching crews, and replacement

of fuses all add up to be very expensive in time

and money. Additionally, these outages

contribute significantly to SAIFI (system average

interruption frequency index) and MAIFI

(Momentary Average Interruption Frequency

Index) reliability indices.

Superior overhead distribution

lateral protection using Eagle

ABB's Eagle is a single phase self-powered

vacuum interrupting recloser. It can be mounted

directly to the pole as a new installation or a

replacement to oil filled single-phase reclosers. It

can be installed separately on single phase

laterals or in a group of three for a three-phase

lateral circuit.

Eagle recloser drastically improves the reliability

indices for utilities simply by eliminating the

sustained interruptions experienced by the

customers due to fuse-blowing schemes and

momentary interruptions due to fuse-saving

schemes. By reducing the number of truck rolls,

the utility can save on operational costs and at

the same time avoid revenue losses due to

outages.

Eagle provides highest interrupting rating among

its class with higher BIL (basic insulation level)

and continuous current rating providing

application from major three-phase feeder

laterals to the end-of-line single phase laterals.
